Very bad service

I paid my account on the 24 December 2015 the amount of R850. I called the customer care to notify them of my payment they have been telling me to email and fax the proof of payment, I did that more 16 to 17 times and spoke to many consultants but no one seem to help me, on friday I called again because my phone was suspended again and I don't owe Vodacom anything, I demanded to speak to the team Leader Patricia Jack (Philile Ndebele) because I previously emailed her my proof of payment, she promised to help me with this matter but to my suprise today when I went to Game they still told me that my account is on Arrears..
