Horrible customer service!!!

Horrible customer service!! My account was canceled immediately in November and I am not receiving data for December and my router has been fetched as well, I was still charged for data and my router for December month, it is impossible to get a hold of someone from rain with billing problems, when they benefit from an email they Will gladly reply but as soon as there is a billing problem they ignore your emails for weeks. Incredibly disappointed with the customer service. And I am not the first person to complain about this!
