Rain internet service provider service

This is my response to Rain data networks request for me to respond to the survey of the quality of their services.

"Please cancel my sim. I no longer require your services. I have requested this previously. Please refund the 479 that you have deducted. I am on the "pay as you use " package and wanted to upgrade to the unlimited 4G 479 package. You have not approved me for this service but you have taken my money. I have not used this service. Please respond. Rain has ignored my request this far. I receive absolutely no response from your service department. I have requested that all my services be terminated and my money refunded (479) but I hear nothing! All my requests are ignored. When someone takes your money without providing the service and refuses to refund you, this is tantamount to being theft. I hope that someone will respond."

I am totally disgusted with the service that I have received from Rain. I have never in all my years been treated with such disdain and indifference. I notice that I am not the only one in this position. Why can Rain not just respond and finalize my request?
