Mobile Phone Incentive Disappeared

On December 7, 2021, I transferred my two mobile phone lines from AT&T to Xfinity. At the time of the transfer I was told by the representative who helped me that I would get a $200 Prepaid credit card for each phone I transferred and that this new incentive had just started on December 7, 2021. The time period since I did this is well over 90 days and I have not received any indication that I am getting those prepaid cards yet. I went to the Incentive Status website on March 15, 2022 and initially it said that my status was pending the completion of the 90 days and it also specifically stated that the incentive had started on December 7, 2021. Since the activation period is now well over 90 days, I went back to the Incentive website but now that status was completely removed. I then decided to do a Chat with an agent to see why the status had disappeared. The Agent informed me that the Incentive did not start until December 13, 2021 so I was not eligible. I have been with Comcast/Xfinity since 1991 and I am appalled that you would  any  Customer with this type of deception - tell them at the time of purchase one thing regarding an incentive, place the status of the incentive on the website as I was originally informed and then when the activation period is complete, change the incentive date! That is an awful bait and switch tactic that I never expected from Comcast/Xfinity. The Xfinity Forum seems to indicate that this same situation has occurred to other Customers over the same time period. I think that it is time that you correct this error and deception and rectify the situation by giving myself and others affected by this situation, the correct incentive as originally promised or if this incentive was some kind of error on Xfinity's part, that some form of compensation be provided to affected customers.
