Porting a cellular number to AT&T

I'm a bit frustrated that I cannot find away to raise my AT&T related issue. I always get to talk to someone who must know my entire life story and then try to sell me something!

Simply, I'm currently a subscriber to Consumer Cellular. They stopped to support my mobile phone because it did not meet their hardware requirements. I just bought a phone (Motorola One 5G ACE locked to AT&T) and now I wish to setup an account with AT&T and port my mobile number from Consumer Cellular.

Carrying my new phone into  my local AT&T store I was told they can not port a number from Consumer Cellular. I then called Consumer Cellular and they stated that there should be no problem porting to AT&T and they also gave me a PIN number for this purpose.

Walking back to the store and they now told me that they could "attempt" to port it but there was no guarantee that it would work and "I could lose my phone number in the process".

So here I am. I do not really need AT&T. I mean I could go to T-Mobile instead but I suppose AT&T would like to add a new customer, based on the fact that they try so hard to sell me something every time I have tried to bring this subject up? (And I used to be a customer for more than 15 years before I switched to Consumer Cellular in 2019).

I will wait here 1 more day to see if I can get some clarification and if not, then I 'll try another provider!
