Bad costumer experience from Vodacom

I had a contract with Vodacom which I cancelled in February this year. I had been paying my monthly fees and they would send me a statement. In April I started receiving calls from attorney that my account is in arrears. I contacted Vodacom to enquire about my account since I have not receive the statement reflecting the arrears. I have not received the statement I requested since 7 April, I have been going back and forth on their Facebook platform requesting the statement so I can see the amount and make payment if indeed I’m in arrears. This has not happened, they have made a commitment to contact me several times but they haven’t. I have been literally BEGGING them to send me a statement! My credit record is being affected amidst all this.
