I cancelled in Feb but you are still debiting me!!

<p>I sent in the necessary documents to cancel my LTE+ service with Telkom becase you could NOT deliver the service as expected. It was ALSO tested by technicians and confirmed. I cancelled in Feb you took the last payment, as expected, end of March BUT since then you are STILL debiting me and i am STILL reversing this. My instruction is to STOP the service and also that would deny you permission to continue to debit my bank account.</p> <p>Please call me and discuss if necessary.</p>
