Horrible customer service

I took up Fiber in November, specially told them my debit day is on the 25th, the did not debit me on the correct date. I call to rectify that in December the did not rectify it. I called again in January, the date was on corrected in February leaving me with arrears on my account. I made arrangements to pay the areas and paid on the 25th of February. I am left with no internet but told I will be billed for March where as I do not have the service. When I request to cancel I was told I will still be liable to pay the full monthly installment for 12 months. The customer service is horrible, you are pushed from one department to another. I regret ever taking up Vodacom as a service provider because WOW, what a ****.
