Useless CELLC call centre agents - cancelling active accounts

how in the world do you simply cancel a client account without verifying anything with the client.

I requested that my 1GB Data line be cancelled and the Cellc agent cancels my Voice contract.

I am now left without any form of communication and the burden is now left to me to go around get new sim cards and beg for my account to be reactivated.

All responses from the Customer care is to be patient, we are escalating and will get back to you.

What am i supposed to do in the meantime.

what a bunch of *********** call centre agents. Everytime I call, I speak to another useless agent, who gives me another story on how they cannot assist me to re-activate my account.
