Pathetic customer service

Ordered an lte-rain data plan only to find that the sim does not work with my router and only works with selected routers. I was advised by a support consultant from afrihost to cancel the existing package and sign-up for a new package that includes the router. Did what was advised and even upgraded to a bigger data bundle, only to receive a cancellation fee invoice of R999.00 which I was not made aware of. I inquired the issue and was told that the terms and conditions allows a 7day grace period in which to cancel before charges will apply. I received the sim on the 9 of jan 2018 and cancelled on the 16 jan 2018...I was told its 8 days from the 9th to the 16th. Not impressed with the customer service or how the issue was handled and have cancelled the pending order with router, might I add that afrihost has no stock of the routers despite them advertising these data deals that states free router. Decided to go with a more competent internet service provider instead that offers better customer service.
