Terrible customer service and follow up

In September 2024, I signed up for Comcast Business internet and mobile service. At the time of the order, I was informed that I would be eligible for $200 gift cards for each line of service transferred from another carrier. Additionally, I was told that upon switching phone service, I could upgrade my phones with a promotion offering $400 off each upgraded phone.

The first issue arose when I had to spend hours on the phone with customer service to activate my lines. One of the lines required multiple visits to a physical store for activation, which also took several hours. During these interactions, I attempted to upgrade our phones, but the system would not allow the transaction to be processed. I was instructed to visit the store again, only to be told that there was a system issue due to the rollout of the new iPhone 16 and that I needed to wait a few days for the system to allow the order.

After waiting three days, I tried to upgrade our phones again and was informed that the discount was no longer available because the promotion had ended. I was advised to wait for the next promotion, scheduled to start in November for Black Friday. When the new promotion began, I attempted to upgrade again, only to be told that since I had already established service, I was no longer eligible for upgrade discounts. Consequently, I am now left with older phones and am forced to pay full price, which was the primary reason for switching services in the first place.

The second issue involves the gift cards. As of December, I have received three $200 gift cards, but I was supposed to receive five. Customer service has now informed me that they are unable to assist me and that I need to contact the agent who started my service, Joshua [Edited: "Personal Information"]. Despite multiple attempts to reach him, I have not received any return calls or emails.
