AT&T AT&T mobility Ripped off on AT&T service plan

I called AT&T to buy the phone and service in December 2019. They offered me a plan where i can trade in the phone with Mobile share plan and they will provide me iphone11 and iphoneXR free by providing monthly credit. I called after my 1st billing cycle when no credit was provided and customer service told me that i will get i n next billing cycle.

I did not get in 2nd billing cycle so called AT&T customer service and they said i have to switch to Unlimited plan in order to get the credit. I don't need unlimited plan and asked them to owner the plan offered to me and provide. I sent them my phone for trade in but still not getting any credit. I called customer service 4 times and every time they escalated to supervisor, loyalty and national but never got it resolved. It is very frustrating to get the credit and i am still waiting for my credit. It is so much bureaucracy in AT&T and i am the victim of their bureaucracy.

I request AT&T to look into my case and please honor the promotion provided to me.
