Zero support from RAIN - DISGUSTING SERVICE

So is rain going to refund our money that we pay in advance? In Lenasia we have no network at all going on 2 weeks very erratic network for the past 2 months as well. Their call Centre guys say their "engineers" will call to try a few settings etc. as it seems to be a router fault. Im still waiting... Since then I have diagnosed the fault myself, the Sim card is the problem. After telling them this I still keep getting template responses with promises that engineers will call me. I now have over 10 reference numbers! All they had to do was send a replacement Sim!!! We've never had a problem with rain before but recently it seems they are going down fast. My business runs only on this connection, is this the new norm to expect from rain? This has to be the WORST ISP in SA, I have never seen a company's service d support deteriorate this fast EVER! Right now there's no fixing this problem, I am canceling and I want a refund for this month. If rain tries to debit my account again I will take this to court. Rain is a circus run by clowns, I will report this to the CPA as well!!!! The 1 star rating is being too kind! Really pathetic service, totally disappointed. I can be contacted via email *** or ***
