Poor service by Rain. Unfulfilled promises and No connectivity!

I’ve been struggling to make mobile calls using the Rain talk app. I called the support line on Wednesday, 4th December 2023 and was assisted by a gentleman named Shaan. He did basic troubleshooting and said the problem was sorted. He said it might be caused by a system glitch showing that my account is in arrears which is not true. My account is fully paid up however my account shows two outstanding invoices. Shaan confirmed that there is no outstanding payments. He escalated to the billing department and said the would call me. By Thursday, 5 December I had still not received a call from them. I called in and was assisted by Mark. He said exactly what Shaan said and also escalated to me billing department. I still have not received any phone call from Rain and still cannot make any mobile phone calls. Payments are successfully deducted but I do not get value for my money. This is very frustrating and disappointing to say the lest.
