Pathetic service, sent from pillar to post

On the 9th June I went to Standard Bank, Simmonds Street to obtain proof of payment for an overseas transaction. I was told that I must sent an email to *** which I did later. On the 10th June, Corporate International rep**** back and referred my query and copied the email to ***. No reply was forth coming so I phone and waited for 40 minutes , 'our consultants are busy....; so I left a message for a call back and nobody bothered to reply. So basically it's almost a week and the service is pathetic , our containers need to be released. Ref No QPQ*** and PPE***. Please rectify ASAP
