Pathetic client service interaction

Sent through an email request on Sunday to 2 email addresses, one being my assigned private banker and the other the personal banking email address for the relevant department, in this case home loans. To date not even an acknowledgement of receipt from my private banker, not unexpected, had the same from the individual in question November 2025 when i purchased a new vehicle, to the extent i decided to go with a different bank for the purchase of the vehicle. It appears someone at the personal banking email address received the request, and this is directly related to my complaint. On Monday morning 13 April, which given it is the start of a new business week, is often the busiest morning of the week for me, they tried to contact me twice IN 1 MINUTE. I was busy at the time with a meeting my side, so couldn't take the call. 3 minutes later receive an email, please note we tried to contact you twice, you please contact us now if you want to conduct your business. Excuse me? You classify that as customer service? In what world would that be acceptable by any pay clients as acceptable service? I expect to be contacted by you as the institution, if you cannot reach me your email should read please provide a convenient time, which I will then provide at which point I will be expecting a call and will not be busy.
