Terrible service from store manager, Coulton. xFinity Store, 8850 Holly Ave Ste F, Albuquerque, NM 87122.

I've been dealing with this problem since September.
I bought one Wi-Fi Extender for $119 using their app on 9/11/25.
The device arrived on 9/15/25.
It did not improve my WI-FI coverage so I attempted to start the online return process 3 times on 9/22, 9/25, and 9/26.
Each time no follow up email was received on what to do next. No follow up messages from xFinity in Spam folder or InBox.

I called support on 9/26/25. After an hour of being transferred to different departments, the Billing department instructed me to return the Extender to the local xFinity Store.

On 9/29/25 I returned the Extender to the local store. I asked for a receipt and was given the following number from an employee named Santiago who appeared to be in charge. [Edit: "Personal Information"].

After not receiving my refund on my 10/1/25 statement I returned to the store and was told to wait one billing period.

After not receiving my refund on 11/3/25 statement I returned to the store and met with a manager named Coulton.
I explained the run around I have been getting and was told there was nothing he could do. His advice was to call Billing which I had done weeks ago and was told by Billing to return the Extender to the local store. 
All this fell on deaf ears. Coulton made no attempt to call anyone and he said there's nothing I can do. 
I told him this was terrible customer service and would I be sure to leave a review. His sarcastic response was "I'll look forward to that".
Unbelievable! Seriously, this manager should be fired.
Still waiting for my $119 refund.
