poor service- VODACOM REFUSES TO CANCEL MY CONTRACT WITH THEM

query reference number: ***, I am very angry with vodacom customer care service. I have been trying to cancel their contact since last year August 2020 until today. When I phone into vodacom customer services, I get put on hold until they hung up on me and when I go to their branches they promise me that my query will be sorted and I even went to vodaworld to attend to the same query and they keep making empty promises that my account will be closed but come month-end I am being debitted. Vodacom has been practically forcing me to keep my contract with them since last year August. I am not happy with their service because they are debiting an amount of R3000.00 everything towards something I do not need anymore. poor service and forcing clients to remain theirs is really bad because now like many other customers I am blacklisted because of their attitude to force high payments on customer's bills to cover themselves.
