Telkom negligence

Hi guys just making everyone aware of the Telkom and Telkom agent’s operations. I’m around May this year I received a call from elite mobile saying I was due for an upgrade for wifi router contract which was running for more than a year without any issues. I agreed to upgrade only if the current contract will be cancelled before activating the new one since I can’t pay two contracts of the same thing. Now Telkom has been debiting my account for two contracts which I never agreed to. I have called and went to a Telkom shop without any help since June while Telkom continues debiting for two contracts without any willingness to assist. This is really shocking me to continue taking my money with a pending case. I received sms from Telkom from June but they never attended my case
