Poor customer service, Horrible in dealing with customers issues

The customers care for rain is very poor and really useless I have been waiting for the billing department to call me for the last two months, I deactivated the sim card and I haven't been using it for months now but they never stopped billing. It's clear that they haven't done their job correctly and was in a call with one agent who told me they don't understand why it wasn't stopped. And while move the issue to the billing department which hasn't called me, I'm really tired now of waiting money calling them to deal with something they could have easily dealt with and even worse I can't see the my invoices on why I'm billed since haven't been using rain for months.

If you were thinking of taking rain don't cause they clearly the company doesn't care about their clients it's all about money for them.

Very poor sir, very very poor
