Poor service from rain, cannot even activate sim card

So i bought the sim card and received the next day. Thought all was well but to my surprise no network, sim not working. I researched a bit and found out that it wasn't activated so i sent through a ticket on their web chat. The guys working there keep promising to escalate the issue to some mysterious "back office" but to date (3 days later) the sim card has not been activated. So essentially paid for service that doesn't exist. Everytime i try to get feedback its a new person who "escalates" and the says it should be activated in the next 24hrs. But it never does. I asked what happened to all my previous queries but the new person insists on escalating it as a new issue rather than following up the previous escalation, and everytime this happens i am stuck waiting another 24-48hrs. I don't like being treated like this please fix your customer service department and back office
