Worst bad service ever!!!

I just called rain about the problem I have with them of always cutting my subscription and saying I owe whereas I don't skip a month without paying ,I was being helped by an Indian lady (accent sounded Indian) and while I'm explaining to her on what has happened last month and they promised it will never happen again,she hunged up on me!!!! Is this really how you treat your customers,my issue is not sorted and the lady hangs up the phone on my ear while talking!!!! This is unacceptable because I have an issue that needs attention urgently so and you have your people hanging up calls!!!!! The worst service ever from rain and it's consultants ....
