my credit ******

In August I went to Namibia, I received a sms stating I have a huge data spendage and have to pay R4600.00 for the account to remain active which I did. Never the less I have a small bill to pay the following month and sitting with a Credit of R3711.01 on the 15th of August. 31 of August this credit shows on my account as \adjustment "and gone is my money. On numerous calls to different departments $300 dollars later no one knows what is happening. I now get told it was for another number I have cancelled which no one also can give me a letter where I have requested that either. No after 3 months I have almost a R6k account to be paid and I have not even used this phone for over 2 months...It is not the first time I have such issues with them. I called yesterday morning. Told them about the sim been ****** and the account problem they opened a querie for the sim but not the account problem. I had to phone again this morning as they promised to contact me via e mail as they are unable to dial international numbers just to find out nothing was done yesterday. <br> """
