No self service no customer service

I have been trying to register for RCS self service so I can receive a OTP, but when I try to register on the RCS website or app I get the error message "we can not validate your information". I called the customer care number provided with the error message on 4 December 2017 for the 1 st time. The consultant informed me there might be a problem with RCS system I must try again the next day 5 December, as I did. I called them 5 times after that on the 5th and 6th of December and getting different answers from different consultants. The last consultant said there is a problem with self service but they do not know when it will be fixed. So I can not use my card for what I want to use it for without a OTP and no other way to receive the OTP without registering for self service. What a let down that the problem can not be resolved.
