Standard Bank the pain of my existence!!

Standard Bank offered to upgrade my account to prestige and I would get my own private banker. This happened but unfortunately I never heard from my prestige banker who also failed to notify me that they were having IT issues resulting in me receiving my cards 6 MONTHS later! My prestige banker has since been replaced. I was in the market to purchase a vehicle and Standard Bank insisted I finance the vehicle through them as I am a prestige banker I will get the best interest rate, I was advised to get an INVOICE not Quote from the dealership in order to negotiate the interest rate. When arriving at the dealership they showed me that Westbank was offering a lower interest rate- Standard Banks response was that I need to prove that Westbank is giving me a better rate which was not possible due to my financial status changing-I am still waiting for a response. Two weeks ago I emailed Standard Bank notifying them that transactions form a week prior were going off my account, and not because of awaiting authorisation but the physical transactions were delayed by a week. This morning I logged on and a total of 9 transactions from last week went off my account yesterday. I will be closing
