Not Telkom, HELKOM

I have attempted to upgrade my data contract three times. Each time my new sim card is sent to an address in Worcester. I have told them repeatedly that I do NOT live in Worcester and live in Cape Town. Telkom refuse to believe I know where I live - the courier company has tried to assist me but Telkom refuses to work with them or me. The last time I went to a Telkom stand and spoke to the consulatnt, I told him what my problem was, he assured me it would not happen again - guess what? Today I get a call from the courier, they are sitting outside my house - in Worcester. I am sick and tired of the disgusting (non) service from them. My bill finds its way to my address so why can't a sim card? BECAUSE HELKOM DON'T CARE!!!!!!
