Escalation via Customer Care is a pointless waste of time

Escalation via Customer Care is a pointless waste of time.

After a month and countless escalations: two very basic, reasonable issues cannot be solved:

(1) why does Snapscan and Zapper not work with Virtual credit cards despite the FAQs stating otherwise (2) why do I have INCORRECT SUMS on my provisional statement - Product Managers cannot grasp the difference between a statement with a numerical error and a provisional statement

I come to the conclusion that the very helpful call-centre staff are simply undermined by an inept IT Product Management team or Business Analysts who simple could not care because they do not have to face customers.
