UTTER HUMILIATION AND EMBARRASSMENT BY FEVER TREE!!!!!

I app**** for an account with Fever Tree on 5th November and was approved, on Wednesday 23 November I asked them if I can still use my old Medicredit card and they told me I had to reapply for Medicredit which I did and was approved once again. So 2 times this month I app**** and was approved. I got a e-mail from them to instruct me to go to Specsavers to collect my card, upon linking the card there was an error and the helpfull Specsaver consultant phone Fever Tree for assistance. Then they told me due to the fact that I had an account before (in covid time- I was without a job which was handed over and debt was written off FUNNY ENOUGH "I made an arrangement and I SETTLED THE ACCOUNT IN FULL January 2022). So how do you approve me 2 times in 1 month and then tell me I should never have been approved AND that I will NEVER be able to get a Fever Tree Account again! How do you humiliate and embarres a person like that!
