RCS CUSTOMER CARE???

Starting from the top, I opened a RCS account solely for the purpose of purchasing something from cotton on online for a birthday present. Seeing that the card I got in store from game had no cover or expiry date so I couldn't place the order, I then phoned RCS to help me sort this out, I was then told to download the RCS app and proceed with a digital card. I downloaded the app which didn't take my details, not to register, sign up, forget password and and and. I phoned them again and i dont know who i spoke to was sarcastic and rude and just told me i have to wait 5 days before trying to log in again, I waited and tried again and still didnt get through in the app. I then phoned RCS once again which they told me is an IT issue and they'll phone me back in 2 hours which of course never happened so I phoned them again, only for the last person to tell me, they don't know what's wrong with the system, IT has been working on a problem for over a month (how is this acceptable towards clients) and that cotton on is no longer a member of the RCS group. Considering all of this happened in the span of a month. Trying to get answers and just someone to actually help me. I am so utterly upset with the process, the service and just opening up an account with them was just the biggest mistake ever because they clearly do not give a damn about their clients!
