Frustrated with Rain

Since the 8th I've been struggling with Rain, I've called Numerous times just for them to escalate, they try and call me once and then tell me they can't get hold of me and then close my escalation. I've asked to speak to a manager my calls get cut, I've been paying for a service and just not getting any help. Too top it off they are now telling me i need to drive to a store to have my problem sorted after spending 200 airtime just for them to tell me they can't help me for the past few days. I've been a customer with them for over a year and this is the service I'm receiving. I;m so frustrated by their lack of urgency as well as customer centricity to get the problem solved
