I have a 3g internet contract with 8ta (10gig). The sim card is no giving an error that it's not valid. Went to East Rand Mall, they said I have to do a sim swop cause they having trouble with the sim card that I have. I'm refusing to pay for the sim swop as it is not my problem that the sim cards that they initially gave to customers are faulty. They then told me to phone the call center and ask them to assist me, which they couldn't. Call center told me to go back to East Rand Mall and talk to the manager, tried to phone, no one answers.
