Still waiting for $200 BYOD promotion after bringing in 4 lines in December/January

Xfinity Mobile was offering "Switch and Receive $200 Prepaid Card" between last December through January 10th 2022. I brought in four lines during that period and the incentive was shown when ordering the SIM cards. The incentives were initially shown on the Comcast Xfinity Incentives (xfinityincentivetracker.com) in February/March. However, in April I noticed the pending incentive just disappeared on the tracker. I didn’t receive any communication about this. I submitted an inquiry at Xfinity Contact portal but got no response. Then, on April 18th or 19th, I called Xfinity incentive line (1-800-526-3268) and a case ticket was created. I was told to expect their response via email in about 7 to 14 days. Since I didn’t get any response after the waiting period, I contacted that line for an update and I was told to wait and contact them again if I don’t hear anything in a couple of days. This kind of conversation has happened for a couple of time. It has been six weeks since the ticket was created. Not to mention how long I had to wait each time for them to call back. This is an awful tactic that I would never expect from Xfinity. I have been with Xfinify Internet for almost a decade.
