No Service from Rain but money gets deducted

Got my sim from them in October and after activation it work great and had no problems even November was great with no problems. Then on 15 December I had no signal and no internet and I phoned them to find out what is the problem. I was informed that my tower is down and a technician is allocated to fix the tower and they are moving me to another tower further away so signal will be poor but I would be able to connect which I agreed to and I was told that after it is fixed I can just reset my router and I would be moved back to old tower. After one hour the signal was dead and to date I had no service and R140 airtime later still nothing only empty promises or the call will be closed as resolved. Send numerous emails to support which goes unanswered as they send a generic email saying your mail was received but nobody gets back to you as a client.
