Terrible call center experience, poor customer service

Terrible call center experience. I have been trying to change my risk address for weeks now. Firstly you are on hold for a long period then when you do get through the consultant tells you they are not able to make amendments on your policy since they are not working for standard bank, they are contractors.. They ask for your details for a consultant to call you back. Of the 3 times I left my details, I only got a call back today, phone rings for a few seconds and then hung up before I answer. Now I received an SMS to say they were not able to reach me and I must call their useless call center again. I am definitely moving my account, my wife's account and all policies we have with standard bank elsewhere
