Worst Bank EVER

Worst ever Bank. Got a private banker, which is never available to assist. International funds takes forever to be paid into the account. It seems like the Bank does not want to work for the interest they get on my money. I can not make card payments because I have to wait until month end for the urgent limit to be raised. I can not transact on the app because I got a new cell phone with the SAME number I am sitting with over R1,2m that need to be paid to suppliers and I can not do sh#t! Will Mercantile pay the increase on my Quotes? Come Friday I will empty my account and go to Standard Bank. Obviously Mercantile do not need my business... or will they refuse me to withdraw my money?
