MTN LTE'S UNACCEPTABLE SERVICE

I have never had a problem with afrihost when i was on the cell c fixed wireless package until they migrated me tol the worst network provider which i did not ask for no where do i recall getting an option to choose what network provider i would like to migrate to and they can see if it covers my area ..now its become a reoccurring problem where mtn suspends my account apparently do to relocation issues yet i have not moved my router since i recieved it all was fine for the first week since i got it the all of a sudden it jusy kept getting disconnected i am really unsatisfied as im paying for something thats suppose to be working but is not when we ask to be migrated to a telkom as they also have a fixed lte i get told is not possible and would need to cancel the package and pay a 1000 rands cancellation fee which i find unacceptable cause i did not ask for this as its on there side and not mine like i say i never got an option to choose a specific network i just got given mtn automatically i think it would only be fair to credit the money back as we keep getting disconnected and unable to really use the data we paid for and they should look into getting the issue resolved or migrating all there clients to a network provider where there wont be such problems cause there are alot of people complaining about this i just feel its unfair to us to have to pay for something that is not benefiting us but making us loose out.
