Rcs group disgusting service and NO help!!!!

So to my utter embarrassment on trying to purchase my husband his wedding anniversary gift at Game (using my store card) I was horrified to find out when at the til trying to pay that my Game card (hosted by the RCS group) was blocked despite having more than enough available credit, because 'I hadn't used it in a while'. My experience from that moment onwards was an absolute disgrace from RCS customer service who continues to play a jolly recorded 'your customer experience is important to us, please stay on the line...' after first a 2 and a half HOUR wait, then a further 45 minute wait, then a 16 minutes wait, then an 11 minute wait on a different day. I'm disgusted by the fact that NO ONE seems to be on the other side of the ONLY telephonic customer services obyss which continues to recite prerecorded nothings keeping u on the line indefinitely. The amount of time and airtime wasted on trying to resolve a blocked card issue, which was not of my I'll doing and worst of all, not informed about has been a true eye opener to the level of service offered to the RCS customer daily. Even more so when RCS group charges one of the highest interest rates out there to ensure they really rake it in while u get absolutely nothing in return. Not even damn help when THEY do something to prevent u from making purchases. Oh and best part of all... It's been 2 weeks since I received their automated email saying someone would be in contact with me in 48hours to resolve the issue. And still not a single call from them.
