Terrible Trade in and Transfer Experience - Please Respond Immediately

I would really like for someone from corporate to reach out to me to resolve this issue we are having with the Castle Rock, Colorado location. 

I have just had the worst Xfinity experience I’ve ever had. We have had to go to xfinity 3 times in the past week, and have spent over 6 hours at the store, to transfer two phone lines over to Xfinity from ATT. We worked with Peter the first two days. We were able to transfer one phone easily and fast. But then we ran into issues with my sisters phone. Peter messed up and network locked my sisters phone by putting in the wrong type of transfer codes. Her phone then was on SOS for multiple days. We contacted ATT as instructed by Peter, but ATT told us it would take 48 hours to put in a network lock ticket and then 7 business days for it to actually be unlocked. Because her phone was in SOS mode for multiple days already, we decided to just go back in and upgrade the phone to solve the issue and ensure she has cell coverage so she can actually work.  So we went in yesterday to do so. Right when we got in, we explained the situation to multiple employees who then told us we could go ahead and upgrade/trade in her phone so that we can at least get her cell coverage. We explained literally everything that happened, even that it was network locked and that a ticket was put in with ATT to solve the network lock issue. We told the Xfinity employees before hand that ATT told us it could take 48 hours to put in a network lock ticket and then 7 business days to correct the issue. Then, Ms Potter, the Xfinity employee,  told us we were fine to trade in her phone and that she was getting $605 with the trade-in from her Samsung Galaxy Fold.  She then guided us through the trade-in process, we transferred all of my sisters data to a new iPhone 17e. THEN at the very end of the appointment when the new phone was already purchased and we had already transferred all of her data, Ms Potter says “ oh we can’t take this in because it’s network locked”. She even had an assistant manager come over to explain why they couldn’t take it in. We explained the entire situation, including that it was network locked to 3 employees and NO ONE thought to tell us they couldn’t take it before we went through the trade in process. I am furious with Xfinity after this. The employees turned a somewhat easy phone number transfer into an absolute nightmare. We are so incredibly frustrated and tired from this. And now, because Ms Potter didn’t note in the trade in contract that the phone was still locked, we are loosing out on the value of her phone if it isn’t unlocked by tomorrow.  The employees at this store are very unprofessional at the Castle rock, Colorado location and don’t seem to know what they’re doing. And because of it, we feel like we’ve been scammed into purchasing a new phone. The employee warranted that we would be able to trade in her device when we presented her with the accurate representation of the status of her phone.

I’ve been with Xfinity for years and this has NEVER happened to us before. I am furious with how this situation was mishandled by the Xfinity employees. It has immensely stressed me and my family out and has taken more time than necessary. I would really like for someone from your corporate office to reach out to me so we can resolve this issue.
