RCS IS PATHETIC - DO NOT OPEN AN ACCOUNT WITH RCS!!

I have had an RCS account since 28 April 2015, however now in April 2019, I am unable to log in to my account via the website, the app or by dialing the *120* account check USD. I have emailed in this regard and was told to provide a copy of my ID document and 3 sample signatures, which I did, and was told that the block on my account was removed and that my account is now active. I tried to log in again, but again, I was unsuccessful- receiving the same error message so I called the customer care line. I answered questions and was told to email my ID document and sample signatures to a different email address, which I did, and was told the block was now removed and that my account is active. I tried to log in again, and again was unsuccessful- receiving the same error message! I called again, answered the same questions and was told that the block had been removed, so I tried to log in while on the call, I was still unsuccessful and received the same error message. The customer care rep asked me to log in using different channels, but I was unsuccessful using any of the options. She told me that this was strange and that she would escalate my issue to the IT department, but that it could take up to 48 hours to resolve, I reiterated that I would be contacted by someone from RCS within 2 days to confirm that the situation had been resolved and that I could now access my account- she confirmed that this would be the case. That call occurred on Monday, 8 April 2019. It is now Thursday, 11 April 2019 and I have not been contacted by anyone, am still not able to access my account (ON WHICH I OWE NOTHING ON!!!!) and cannot even get through to anyone on the customer service line- after waiting for over 20 minutes to go through to an agent!! This is completely unacceptable and cannot be likened to customer service in the slightest!! In the first place, it is absolutely ridiculous that although I have had an account with them since 2015 and owe nothing on it (which implies that I have received the statements sent to me as I have paid them) my identity and contact info now requires verification, and in the second place, that I am unable to contact anyone telephonically and have not received any response from them, either telephonically or by email!! It strikes me as odd since they harass any person who is unfortunate enough to have their number on one of their call lists by calling incessantly- so why, when I require some assistance, is it impossible to speak to anyone or even get a response?!! WHAT IS THE POINT OF AN ACCOUNT THAT I AM UNABLE TO USE?!!!! Can someone provide me with some assistance URGENTLY, today if possible!!
