Pathetic service

If its not one thing then it is the other with cell C! I am fed up (I am writing this on behalf of my mother as she is unable to do so.) This time i need a sim swop. I got a laptop with data.. The sim card is lost, so we did what we know and purchases an un ricard sim from a local store. Now i call in to do the sim swop and get told that i am unable to do a sim swop and must go to the store. Here is the thing. I would go to a cell shop of they did not close down BOTH stores one im shelly beach and one in Port shepstone oribi plaza. The nearest branch is in durban, i am blind and I have no means of getting to a store to do this sim swop. I explained this to the lerson on the phone hence i called in. My children are not around to assist me and besides that I have to now travel fuel up someones vehicle and still pay an odd 100 and something for a simswop. If its not cell c messing up my account or upgrade then its not cell and their service. Now i have to pay for a sim card that i cannot use or receive because i have no store near by. No assistance whatsoever from anyone. I need assistance and answers!
