WORSE MOBILE SERVICES PROVIDER IN SA

I wish we could give 0 stars, worse company in South Africa, I signed up for home internet package, and it was stated that I would be paying upfront, which I was in agreement, they were quick to take bank card details and debit my account, I paid pro rata for JAN even though I only received the device on the 31st. Then on the 7th I received an invoice for R1092 but my monthly agreed package was 399, this was for FEB and MAR apparently, so even after paying 645 upfront for FEB, I was billed for FEB again, plus MAR. I then enquired and was informed that I was in a credit and would not be billed (this was a lie) when I cancelled the service, on the 19th I was informed i need to settle my account of 467, (MAR invoice) so they still want two months billing for 15 days of service. This company reeks of incompetence and lack of knowledge of their own products
