BAD BAD BAD SERVICE

On 23 August I went into the Melrose Arch branch to tell them that it had come to my attention that they had the number for which they were billing me was different from the Sim in the modem they had given me.I pay for a 2 gig contract and this is a 1 gig contract. I also gave them the name of the person who owns the number I have. I had previously told them that my(supposed) 2 gigs of data does not last as long as other accounts with 2 gigs. I was phoned 2 days later to be told they were looking into it. On 7 September, I went in again and Siyabonga (Manager) told me I shouldn't expect good service because no-one gives good service and he mentioned Cell C, Vodacom and MTN as all giving poor service too. He told me he would escalate the problem and call me. Needless to say he didn't. On 10 September, I called and left a message for Winnie or Siyabonga. no one called. On 12September I called and spoke to Winnie, who said she would find out what was happening and call me back. She didn't. I went in again on 13 September. when Winnie was asked if she had called me back, she shrugged and smiled. Surely it can't take 3 weeks to sort out this problem!
