Telkom don't know about service delivery

Good day i opened an account at Telkom of a 4mbps internet line. It's been more than 2 months now the mobile sim (integrated sim) of 1gb you receive with it to use in a mobile phone or portable usb modem just cant be activated. I've been at the Telkom store N1 city branch more than 4 times now nobody including the shop technician can activate the mobile sim to work in my sony xperia L1 cellphone. I reside in Wellington area now Telkom expect me to drive to N1 city Cape Town just to get this fixed and I was there as i said more than 4 times they simply can't assist me in this matter this is really bad service delivery I would like to cancel every account I have with telkom it's like Dstv there is only one way and you must work with telkom even if you don't want to because you must rent there landline. I've been told Telkom N1 City Cape Town is the nearest store who can assist me i feel so bad that i opened accounts with telkom.
