Pathetic service

Ever since having my builders card ,its been a terrible experience dealing with ur call centre and the account itself.Either my card is blocked due to *****,then i have to call in ,then it was having to go instore to verify myself,then it was i must get a new card. What a painfull experience! The latest i cant use the app,this is how i pay this account,called in was told 24 to 48hours i wil get a call from the ***** department. I phoned again 5days later then got told,sorry cant help u.

So what am i to do now? Or do i rather just cut my losses and close this account?
