Rain bad customer service

I subscribed to a rain mobile Sim Card for almost a year without experiencing any major problem (except a few minor problems that got resolved) until about a month ago again. I wrote to Rain several times regarding my intermittent internet connection issues. I have been Ignored in all my numerous attempts however to get my problems resolved (I have got messages and reference numbers to prove if |I have to). I wrote them e-mails and messages on their options for communicating with them ( they do not have a telecommunication option. Their instant messaging is constantly congested and if you get disconnected by any chance, you have got to start at the end of the queue again. It is even difficult to get through this messenger as sometimes it is unavailable or disenabled. My main problem though is that I still experience quite serious internet connection issues with rain network and Rain is Ignoring all my complaints this has been happening for more than a month now as indicated. Getting billed at the end of the agreed term for such poor service is really bad and am thinking now of ditching Rain for a better service provider albeit at a higher cost. My rain connection is still very very bad as I am writing this and I believe shall continue being like this until my next billing period.
