free peacock

On 6/27/23 I received an email from Xfinity offering a free Peacock subscription for 2 years because I am a gigabit subscriber.  About that same time, I could no longer access content on Peacock without a subscription.  I have called numerous times over the last 2 months without success. On 8/2/23 I was given an ECM number (ECM0003063147) and told it would would be fixed within 14 days. How can I get this resolved?
