The customer support at RAIN is such a disappointment!

The customer support at RAIN is such a disappointment! I got billed twice after I never got any assistance with a request submitted regarding my Rain SIM. The request was clear. I explained how I needed help/advice/cancellation, if need be, regarding the change of option I requested. This was in December 2020 The response to inquiries either takes forever or it never happens at all! It's like they randomly choose when and to which inquiry they will reply to. When they do eventually reply, the reply is a lousy, irrelevant generic reply. I got billed twice for the one SIM I have not been using for 2 months and for which I had requested assistance with either updating or cancelling! They conveniently rep**** to my latest inquiry to tell me that I had only done the cancelation yesterday and that they have no record of any previous inquiries from my side! Only after they had been billed twice , they reply to tell me I cancelled too late!!! I have been asking for help since December 2020 to avoid double billing!!!!!!!!
