VODACOM you are a joke!

Vodacom are the most ***********, useless service provider in the cellular phone industry. We have not received a statement from them for more than 8 months! In spite of us visiting the Vodacom outlet Garden Centre, Cape Town and calling their service centre a number of times they simply refuse to send us an invoice and statement!! One thing they never forget is to debit you each month. We complained to Vodacom about a hefty bill of R6700 for the month (that is for my wife, my son and myself). The following month the bill went to R 8100. We asked for a detailed statement once again and we had to go to Gardens centre again. This is now 3rd month in a row we have asked for an invoice and statement and yet they still can’t provide us with one. How useless do you have to be to not get this right!! This is incredibly frustrating and totally unacceptable and every time you call them to address the issue, you deal with someone else. CAN SOMEONE HELP US PLEASE
