Sick of Standard Bank

I been a Std bank customer for more than 10 years with a prestige account and impeccable credit rating, a while back +-4 years I went in for a home loan they they turned me down, the next day I was approved with SA home loans. Few months ago I app**** for a personal loan they turned me down AGAIN!! Same day got a personal loan at Wesbank. A week ago they had a glitch with there online banking app and double paid each of my beneficiaries, I called in numerous times even went into the bank, my so-called prestige banker also did nothing! I still have not been paid my money back and I'm being charged interest on my overdraft for money double debited due to there glitch, f$#^ Standard bank!!!
