Bsit-WiFi - Poor poor Service!!!

I would not recommend this Internet service provider to anyone. I run a small business from home and am completely dependant on internet access to do my business. When you phone these people for support when you cant connect via their Rain internet service provider they promise to resolve the issue and get back to you, but never do so. Today is the second day i am without internet and still i havent received any feedback from Bsit!!!
