Totally disappointed MTN customer

MTN is really dissapointing its customers, I have the R269 uncapped home LTE, at first it's reduced to 2meg line which was ok.. Than in less than a month it reduced again but to 1 Meg line and now again it reduces to 512kbps... Like what the **** is wrong with this service provider.. Do they want to loose all of there customers?? This is utter bull**** and nonsense.. We can't keep paying the same price for *** network speeds. Sorts urls self MTN or url will see urlselves go down the drain.. Keep the speed at 1meg line or it's useless having url as network provider.. Rather go telkom if yourl can't prove urlselves
