Inconsiderate call center

I called the Starhub call center. It asked me to press many buttons and gave me announcements of promotions that do not interest me. It also gave me a message that I have heard more than 1,000 times, about the call being monitored for training purpose.

How inconsiderate of the call center. Don't they have any consideration for their long suffering customers? I was then asked to enter my mobile phone number. I did.

A voice answered. May I have your NRIC number?
TKL - I just pressed my mobile number. Surely, you can retrieve my record from it?
Voice - sorry, I don't have access to that number.
TKL - Why did your system asked me to key in that number?
Voice - Sorry.
TKL - Please pass my feedback to your management. Do be considerate to your customers. Do not make them waste so much time and do a lot of irrelevant steps.
Voice - OK.
