Poor Coverage. Pathetic Customer Service

Very disappointed with the customer service. I've been sent from pillar to post and given template answers by the agents. I have done everything they recommended but still, the network connectivity is poor. I was told my case has been escalated to the relevant department but no one even bothered to contact me to try and resolve the issue. Instead, I was sent an email to say my tickets were resolved. If Rain is not honest about their coverage they should lure customers to taking up their services because it is ****************.
