Is this the level of competence we are to accept?

I was offered a pre-approved credit card via Clear-Score. The whole process was promising until it came to acceptance - on a credit limit that was 33% lower than was initially offered because they were "unable to verify my income". This despite having 3 months worth of bank statements and a detailed payslip! I really have to question the calibre of staff who seem incapable of performing a simple verification. Capitec got my application completed in a morning without any issues and with the limit originally promised. Discovery "bank", please stop wasting people's time and please do not contact me now or in the future.
