Monthly billing changed without my consent

I'm not happy with M-Web increasing my monthly billing with notifying me via email and not giving me alternative options, we must just accept it. Apparently Zoom, that supplies my Fibre line, have informed them about the price increases. As a result, M-Web will be adjusting my monthly fee. They are also increasing my line which I did not ask for? This is an increase of R210 extra per month which I have no choice but to pay. Surely, its not the customer's fault that existing line speeds have been discontinued, if that's the case, then they must offer the same amount that we have signed up for and just change the line speed accordingly. We did not tell them to discontinue the cheaper line speeds. They are just greedy!!! This is daylight ******* and they have no accountability for it. How can the normal man off the street afford these ridiculously priced packages now??? Don’t even bother trying to get through to their customer service because you hang on for more than 30mins to try to get assisted. I wish I never signed up with these *******!!!!!!
