Had to use Twitter to cancel my membership because emails receive no response

My husband and I have been struggling to cancel our gym memberships since the start of June and the debit orders have been going off each month despite reassurances that the request had been submitted. We weren't receiving responses to our numerous emails and can't call because we have immigrated. As a last ditch effort I saw that there were some responses on Twitter so I sent a dm on Twitter and actually got a reply. After three months we have finally managed to cancel our membership. So to anyone else struggling, and I see there are a lot of others, try sending a message via Twitter.
