Pathetic Virgin Active

I started a Virgin Active membership about a year and a half ago. Always paying my debit orders even though I moved away and did not use it because there was no Virgin Active where I moved to. Long story short, finally moved back the where I app**** for my membership. I decided to cancel my subscription and had to pay 50% of my outstanding monthly installments as per agreement. I went in to the branch and requested that I would like to close my account and pay all the outstanding amounts, the receptionist printed the documents and I paid the outstanding amount. We all signed and off I went. A month later Virgin Active head office stills phones me to tell me that I owe them money, and want to keep me liable for the probable mistakes made by their team at their branch where I closed my account. I asked the lady that day who assisted me “are you sure I owe Virgin Active nothing” where she rep**** “yes mam” and to this day Virgin Active still phones me rather than finding the problem on their side and investigating where the mistake slipped in, and maybe sending me proof that there was a error, no Virgin Active rather accuse you of outstanding payments not serving you with any proof whatsoever.
