Discourteous call from *** Virgin Active Rep

Virgin Active has always been a benchmark company when it comes to service delivery. Like one of the best companies i have been with. During covid 19 i cancelled my membership due to covid protection reasons. I have been under the impression that my membership is finished. however Today at 15:34 I received a discourteous call from *** one of their representative. Saying that i owe them R6500 or so, In return i politely asked that i have not been to the gym in months how can it accumulate to that amount. And the representative refused to provide me any details on that, so much so she hung up the call on me saying your account will be handed over bye. PLEASE I would like to know why so spiteful to customer who has been with virgin active for maybe 4 years or so.
