Very unhappy client

I had a vumatel line which constantly was down, so I requested for a new line, the new line was installed and I requested the vumatel line be closed. A week later I got an invoice double debiting me for my new line and old line and noted that the line was not closed

It took a week to close the line, I was still double debited and am yet to get a call back from MWEB to advise me when I can expect my credit for their mistake

To say I am fuming and out of pocked as well as the new line with the new provider also dipping regularly I am wondering if MWEB is any better than ESKOM at this point !!!!
