Credit limit increase

I app**** for a credit card limit increase on Wednesday ( 18 September 2019) AT A BRANCH! because I could not get assistance over the phone or app.

I went to the branch with my 3 months bank statement and payslips but these were not requested.I was told I would receive feedback in 24 hours but i got ZERO communication.

I call this morning to follow up and I'm told I need to submit proof of income, but no one knows where i should sent the documents. I have being told that an email request was sent for the documents but i have received nothing. I even called to confirm my email address, BUT STILL NO EMAIL! NO CORRESPONDENCE ABOUT THE APPLICATION! and NOTHING CAN BE DONE BY YOUR "TEAM OF BANKERS"!!!
