MTN - Bad bad service

I live in a rural community Thabazimbi -Dwaalboom. MTN is with no signal at least once a week. Some times for two or three days at a time. We are 100 km from nearest bank. We relay heavilly on internet banking. Also doing business on the internet. We have to pay monthly for our contracts. If I don’t pay - no service. If MTN have no service I still have to pay. I pay the same amount as some one elsewhere in South Africa. I thought MTN was number 1 service in SA. Vodacom here I come.
