Intercare Glenfair Admin Inconsistency...AGAIN

Today my husband had to see a GP, so as usual we go to Intercare Glenfair. He shows up for his appointment, and they tell him that we are not on the system. We have actually been going there FOR YEARS - so how, did you just throw away or delete our information because at my last visit I opted to pay cash, due to your consistently terrible accounts department? This is not the first time we've had nonsense with their administration, but it certainly will be the last. I don't ever plan on going back and I do not recommend anyone else go there - unless you enjoy sorting out their admin nonsense.
