Backend undermines customer service again

Outstanding service @ ABSA Nicholway to complete my successful application for an ABSA Credit card but the "backend systems" have failed again. Despite an agreement to debit my cheque account for the full outstandings on 3 May, nothing happened so I did a manual EFT today. (Well even FNB Card Div are capable of falling at the first hurdle.). But ABSA have gone a step further. Despite applying with proof of new address, my old Virgin card address has been used on the credit card statement. So now it's back to the jolly bank branch I go with ID, proof of address....I realise merging databases might require more than a little attention but come on! I despair.
