Vodacom - easy for them to bill, impossible to stop them incorrectly billing

Vodacom

For the last month I have been trying to disable a recurring data bundle that I no longer want. I have emailed and had different answers from every agent. I have had data roaming enabled, which I was told I needed in order to log into your website in order to cancel this. I have now logged into your website, and have been told that I now need to phone in order to do this. I am overseas.

I am at my wits end, To do something so simple has been an absolute nightmare, and every month you continue to bill me for something I do not want!!!

WHY IS IT THAT I CAN PAY FOR A NEW SERVICE SO EASILY ONLINE (MONEY IN), BUT TO CANCEL IT IS AN ABSOLUTE NIGHTMATE (MONEY OUT). YOU ARE MONEY GRABBERS!!!!

Please sort this out.

Next I would like to change the contract I am on. HOw much of a nightmare is this going to be ???!?!?!?!?!!!!

Please treat your customers with respect and stop just grabbing their money. You are disgusting!!!
