***** when it comes to cancelation to which I am entitled to

I've been a loyal customer for the past 8 years. Quick to contact you to upgrade but what a **** show to cancel a contract.

I want to cancel my data sim (not my main contract) as the contract for the data sim expired. The store who did all my upgrades (Paarl Mall) is not able to help me. They just throw their arms in the air and tell me that I should call 135 or *** to cancel the contract.

How on earth is a physical shop not able to assist me to cancel the contract? The very same shop who activated the contract?

When I call the numbers given you have to hold on 30 minutes after which the phone is put down in your ear or you are put on hold. How will I cancel this contract if the phone calls are unsuccessful and the actual shop is not able to assist me?

Really considering to move from supplier - oh wait, I cannot because I am not even able to cancel a data sim.

PATHETIC.
