I want my money back!!

After almost 5 calls made to Vodacom I still haven't received any assistance, I needed them to refund me the money I paid prior my debit order going off, I'm being told I need to send proof of payment to an email address which is not even ****in working!!! Can you guys pay back the money and further cancel my contract, this is the most appalling service ever. People shouldn't bother signing up with you. We pay lots of money for your expensive ****
