PNP Store Account Nightmare

We have app**** for a PNP Store Account that was approved on 26 Jan 2022. Since then, we have not been able to use the card at any PnP Shop. It gives an error at the till point “ REASON 39: No Store Account “ We have been phoning both PnP and RCS Call Centres every day since 30 Jan 2022, with no help at all. Every time they tell you, that you need to be in the shop, we go to the shop, nothing changes, you get transferred from department to department. Then the call gets cut, and you have to phone back, hold on for 45 minutes, and then explain your story from the beginning. Yesterday, 5 Feb 2022, we spent just under 4 hours with them on the phone, telling us we need a new card, which then wasn’t working either. I find this pathetic!! How can no one know how to fix this problem??? I see so many people complaining here about the same problem. If this is the case, I do not even want this account!!
