Worst customer service ever!!!!!

I joined the rain family last month and the internet worked perfectly until they debited their money on the 1st of July my router suddenly said no service till today 17 days later,I’ve sent countless emails and nothing has happend,I’m not happy at all!! Because come month end I’ll be paying for services I couldn’t use half of the month this is by far the worst customer service eveeeer I’ve even dmed their Facebook page since theyve said it’ll be solved,this is honestly tiring I’m five to cancelling my contract
