useless customer service

I have spen 4 hours on the phone in the past 4 weeks to sort out my account and i heve been routed from operator to operator. Phone calls have been ended. All with no resolve. Your service is useless. I cannot pay my account if you do not pick up the damn phone. I cannot sort out my router if you do not pick up the phone. is everyone just on holiday and to hell with the customers???
