No contract with Telkom

Telkom: we paid for uncapped WiFi. This is the beginning of the month and we can't connect our TV with one cellphone then everything buffers. We have been customers for 3 years. Never has this happened. Why for the last two months is this line of ours buffering so much? How am I suppose to work from the comfort of my own home and please our customers if we can not connect our devises as we use to. This is utterly unexpected. We will be cancelling our contract with you. And please viewers. Do not go to Telkom with any contract as they only do as they please. Thank you for being our horror in this time
