Braech of contract by Supplier

I have a contract with Virgin Mobile and I transfare instalments from my bank or deposit into supllier's bank which is Nedbank. My best convenient method is transfare money from my bank into Nedbank Account.<br> <br> My last instalment was paid on the 30th 0f September 2015. The deposit slip was faxed to the company's fax number *** at about 14:30. I then confirmed receipt thereof with their customer Care employee [name forgotten]<br> <br> Yesterday I received an SMS that my lines will be suspended because of failure of payment. I called the Customer Care office, spoke to Lerato who confirmed that the system is not showing that I paid and for that matter I am in two months arrears. What a shock.This is not true,does the office listen to the recorded conversations?<br> <br> True to their words my lines are suspended, I have paid their system is not picking up my payments even after 48 hours let alone a month. HAYIII BOOOO.
