Rain Customer Service? Not a chance!!!

During June this year I signed up for the Rain One deal. Delivery of the OPPO model 5G CPE modem/router with the sim cards was promptly done and connection and setting up was smoothly done. Although I do not have 5G in my area the modem works well and I cannot complain about its performance. Then the snag hit. I cannot access the modem setup configuration to change my SSID and password. I called them about it and Rain confirmed that I should be able to have full access to the modem. I was promised a replacement unit which to this day has not arrived. After several phone calls, emails and whatsapps nothing has been done to resolve the problem. Not a single phone call was received from Rain about this. They just issue you a new reference no. The no's received so far for the same problem: ******541 Every time you are told they will escalate the issue. If you request to speak to a more senior person or the person in charge to where the problem will be escaleted to, you get promised they will phone you and that is where it stops. This is the worst of customer service I have encountered. Even the email addresses they provide to report problems bounce. How's that for service? This seems to be a benchmark for the cellphone companies in general to send you on a roundabout when you enquire about a problem. I even approached Oppo directly about this problem and the service and feedback was excellent, however it was pointed out that the software on the modem is a Rain issue and as such there is not much they can do about it
