MTN Bad service.

I signed up for a new contract 20 meg LTE fixed line and MTN Edenvale. At now point was i told that the area were i stay and were router will be, must have LTE Tower. I was given the contract, when i plugged in the router it did not work, i phoned MTN 135 number and spoke to many consultants and received different answers as to why I am not receiving service. I was told to take router back to shop for them to set it up. after a technician from MTN gave us the settings and we did it on the router. returned the router to MTN shop on 2 occasions and was told on both occasions it is now fine and i will receive service this still did not work when i got home. on Saturday i traveled bact to the store an hours drive from home after being told by MTN to take router back to store as the address they captured on the contract was wrong and this is why it is not working at home. i returned to store and corrected the address. Returned home hours drive and still did not worked, phoned MTN and again some setting was changed, and then get told by consultant that area is not covered by MTN, and i should cancell contract. i informed the store accordingly. then get told that the manager will get back to me. only after sending a message this morning the manager phoned and i was told to use a different router as he thinks the router that was supp**** could be faulty. after changing settings on old router the service worked for about 30 minutes. Again ask the manager to contact us as service is again not working. This has been going on now for 5 days. i now must pay 2 years for a service i cannot use as according to MTN there is now service in our area, but according to MTN store there is service and they cannot cancel contract. all i want is for MTN to make up there mind if there is service area or not. i can be contacted on ***
