Filing a complain

Annoyed with the customer support. I signed up for Xfinity mobile service for an e-SIM on July 18th as the person offered me 2 years $0 per month service since I have internet also and $100 e-gift card but my device was not unlocked at that time. The agent told me “no worries, I will mention in my notes and for now you take the internet service and once the device is unlocked you can get a new line free for two years and $200 gift card. He also provided me with the order number [Edited: "Personal Information"].

Guess what on 8/1 after waiting for almost 40 min I got my e-SIM activated and the agent said “maam the other agent gave false information and you won’t get free line for two years and $100 gift card deal is already expired”. 

I felt like being cheated and frustrating  to see different agents giving different information.  

Hope a manager at Xfinity sees my post and gives me the credit that was promised to me. I can share screenshots of my chat with the agent I spoke to on 7/18 if needed. 

Thank you.
