Married At First Sight UK's Adam Aveling launched into an expletive fuelled rant as the final episode of the show did not make it to air on Thursday night.
The 26-year-old, who is partnered with Tayah Victoria, had been geared up to watch the end of the series only to find that a much older episode was on instead.
The mistake was not explained to E4 Viewers or the chaos, who were left wondering what had gone wrong.
Amid the chaos, Adam took to social media to brand the fiasco an 'absolute s*** show'.
"What an absolute s**t show!!!!!" he fumed. "Shocking this! Good job I cancelled the post I had scheduled for 10:00pm".
Adam then promised to share details of the unaired show, "I will drop all spoilers" he vowed.
He went on: "Bit of an update, heard absolutely nothing from e4/Channel 4, been waiting for this episode for 4 months and this happens and nobody tells us anything, f***ing shocking."
"Someone from e4 tell me wtf is going on!?" he raged.
Adam has since deleted all but his first post on Instagram.
On Wednesday E4 offered an apology to fans and confirmed when they will be able to watch the final instalment.
A Spokesperson said the episode will be available to watch Friday 1 October at 9pm on E4.
The reunion show on Monday 4 October will go ahead as planned.
A spokesperson for E4 said: "Following the incident at the weekend, ongoing technical issues have meant that Thursday night’s episode of Married at First Sight UK was a repeat from Wednesday 29th September.
"We apologise to the fans of the show and have worked hard to get the episode to you this evening at 9pm. We hope that when you finally watch it you can find out whether Amy & Josh, Tayah & Adam and Morag & Luke renew their vows."
Fans of the hit TV show were left gutted when the channel suffered a mega glitch and showed a repeat episode instead of the final instalment.
The couples were also tuning in at home and were just as disappointed when they realised they couldn't watch the second batch of vow renewals.
Morag took to her Instagram Story to address fans of the series and said: "I mean I have no idea what's going on so I'll just continue packing and pretend that everything's fine! I'm fine!
"I mean such a shame that there wasn't any glitches in editing, just saying," she added cheekily.
The Essex native later added: "I mean guys, generally, I'm so sorry I can't believe this. This is mental, this suck as much for us as it does for you guys."
"Wow they're really dragging out this cliffhanger playing last night's show again, aren't they?" Amy told fans in a separate Instagram video, before posting some hilarious memes about the glitch.
E4 apologised to viewers via Twitter, but they didn't confirm when the final episode would actually be shown.
"We’re aware it’s yesterday’s episode of #MAFSUK playing out this evening and apologise," the channel posted.
"It’s all down to our ongoing tech issues which we’re working hard on. We’ll update here as soon as we know more and when you’ll be able to see the final episode of MAFS UK."
Strictly star AJ Odudu also took to Twitter to explain why the spin-off show wouldn't be airing tonight either.
She tweeted: "Oi oi! @E4Tweets have had a little (massive) technical glitch so won't be showing tonight's #MAFSUK final. But fear not, there'll be no spoilers on #MAFSAFTERS as that won't be shown either. Both coming soon."
E4 later added: "To confirm, #MAFSUK and Afters won’t be playing tonight. We’re sorry again – we’re working to make it available on All 4 and E4 as soon as possible and we’ll update as soon as we know more."
Tayah, whose vow renewal was also set to be shown, took to her Instagram on Thursday evening as well to apologise.
Sharing E4's post, she wrote: "Sorry guys, I'm not sure what's going on and I know as much as you guys do. I'm sorry for no explanation but we will hopefully be back for the last episode soon."
