Pathetic vodacom service

I took out a sim card contract with vodacom and when I received the product, it was not what I wanted, as the deal was a home internet sim card. I then spoke to an agent to cancel the contract and for collection to be made, I received a message to confirm the cancelation request. A few days went by and the device was still not collected and I contacted vodacom again, just to find out that nothing was appearing on the system about cancelation and collection. The agent then requested cancelation again and collection, this after numerous attempts to get ahold of vodacom customer care agents.

The device and sim card was then collected eventually. My problem is that my account is still being debited after I haven't used the simcard and requested cancelation 2days after taking out the contract and I am still receiving invoices and statements.

The service is pathetic and customer care is even worse, as they can never assist with a query or want to give a customer service number to phone which never works.
