Rain Worse Internet provider EVER!!!

Rain Internet is the worse internet provided ever with the most pathetic customer service, I've been trying to get their attention for 3 weeks now by sending 100's of emails, messengers on Facebook, calling the Centre , and 3 weeks later I still haven't receive any response or help from them due to my problem that i have coverage (internet connection), i will have connection for 2 minutes and than it will disconnecting for 2hours !!! I did not have this problem when i got the sim card and than suddenly 3 weeks ago there is no signal and disconnecting non stop. the worse part is they don't care to assist in any matter as long as they receive their monthly money they don't care about their customers but when i tested them saying i wanted to upgrade they phoned me the same day to get upgraded and more money out off me. I strongly not suggesting to use Rain service as you will waste your time and Money!!!!!
