Poor customer service from Standard Bank

I was called by a consultant from Tyger Manor to upgrade to Private Banking. I was transferred to a Sandton consultant who was to email me the offering, to which she did not after confirming with me she would. I then called the 1 April to the Customer Service line had to wait on the line for 30 min, I eventually disconnected the line This is not how you would handle customers you want to upgrade in your product offering to private banking This is extremely poor service
