Poor Service Vodacom

I had a contract with Vodacom Number I ********** Cell nr ********** 828. Last year November 2017, I received a notification that my contract is due to expire. I phone the call center to cancel my contract. I also asked the person as to when is my last payment due on which he answered in December. I then waited until the debit order went off my account and instructed my Bank to cancel it. During the end of February I was contacted by Vodacom, informing me that I still owe them money and that the last premium was not in December but in January 2018 and there is a fee of R100 because the debit order was stopped. On the 5th of March I went to the Vodacom shop in Montana and asked the cashier what my outstanding amount is. He then told me it is R359.00 of which I paid then. Instead of crediting my account the cashier credited I ********** . So according to me everything was in order. In April 2018 I again received a phone call from Vodacom informing me that the balance was still outstanding. I then went to the Vodacom shop to inquire and only then it was discovered that my payment was credit to the wrong person's account. I again spoke to the call center and asked what should be done now. The lady said I must send a mail to ********** which I did on the 11th of April. I also received the confirmation that the mail was delivered to the said email address. On the 12th of April 2018 I received a text informing me that my account has been handed over to legal and an amount or R440.00 is due. I have phoned the legal department and explained to the lady there and all she said is that they never received the mail, although I have proof that the mail was delivered. Because of the fact that I do not get service of vodacom to sort out this problem causead by Vodacom in Montana I decided to request the help of Hellopeter
