DISGRUNTLED CUSTOMER

I have been trying to get my standard bank credit card limit increased since last year through the customer care number and it has been declined 3 times without a reason. i then went to the standard bank branch in greenstone on the 25th of April 2023 with all the required documents hoping to get the matter resolved and a reason as to why my application was declined but i still didn't get a reason why and i know that I've got a clean credit report. The gentleman (Fuzi) who was assisting me said he will send my application to the arbitration department, which he did and contacted me a day later to finalize the application. i went back to the the bank to sign and finalize the application but to date i have never received the increment that i have asked for and no one is saying anything to me. i phoned the bank on the 03-05-2023 and i was told that they don't get help from my employer with regards to the confirmation of employment, and that is not true i fail to understand why they need to confirm employment since i and their existing customer who also provided them with my payslip and a 3 months bank statement. I am rally not happy with the way standard bank treat their customers. i have lost all my money in my account in October 2016, logged the query with them and i was told that i gave away my credentials to the ****mers over the phone. i feel like standard bank don't value their customers.
