Humiliation and poor service

I am very dissatisfied and frustrated with the service I am recieving from Virgin Active. On the 18th Jan 2023 I went to Westville branch to sign up for gym as I have used virgin active before. All went well and we were signed up with my son, and were visiting gym with my son without any problem. On the 21st of Jan I also signed up and paid for 15 swimming lesson for me and my son. Our 1st swimming class was on the 23rd of Jan, my sons V club card was not letting him in but mine was okay, anyway they let him in. After the class when we were leaving the gym I decided to sort out whatever was holding his card entry. To my suprise when I spoke with the receptionist who was there I was told I owe +\-R13000, I freaked out because I know I have no debt with Virgin active, all was settled. They say it an arrears for around 2012, I am telling them whatever was owed I settled hence the account was even removed from Transunion, my profile is currently sitting at favourable because I have no default nor arrears under my profile. They promised to sort it out with their Lawyers MBD but till todate it back and forth. When we phoned MBD with the branch manager the lady we spoke to from MBD confirmed that the account is closed on their side hence they don’t have any records for my account on the other hand I have a screenshot taken from the branch PC showing arrears of +\-R13000 under my name. I have been demanding answers since then till todate the is no clarity, the branch keeps on saying MBD is failing them. I have contacted virgin active head office and the branch there is no response. I ended up requesting for a refund of classes I just paid for swimming and for the personal trainer, and I am told to contact head office which is non responsive. J am so disappointed and frustrated😣.
