Cox Promised Credit for 2 Months, only gave 1 month

I saw the same thing. The chat rep (more like bot) told me it would be credited within a couple of days on my bill.  My statement is almost 2 weeks old from the time they sent it to me, and I figure they would have done something about it before now. I have determined that I'll see that credit before I pay any of it.  I have an email and I have screenshots of the website stating it will be credited.  Just waiting to see if they take care of the 13 year plus customer.
