Disappointing, pathetic service

My 18 year old son joined Virgin Active Mitchells Plain last year June '21, monthly cost R440 and then my 16 year old also joined, monthly cost R280 being debited both amounts from my eldest son banking account. Virgin Active started debiting odd dates and odd amounts started debited the amount of R1110 per month. When I contacted them to query every time will look into the matter and get back to me, numerous times, eventually I went in at the branch spoke to Manager, explained to her what the matter is all about. She told me to email her the bank statement and sort it out for me.... till today she never got back to me. Today again an amount of R1110 has been debited. As a mom I'm furious, their service is pathetic. Honestly I told my son not to sign up with them cause I heard a lot of bad service of Virgin Active.
