Suddenlink / Optimum review: I would like an apology for each time I had to call and remain on the line for hours and retell the story

In June of 2022, a large truck drove through our neighbor hood and knocked our cable from the pole. After calling the repair into Suddenlink they put in a ticket with the 3rd party service technician's they use. All of my services are bundled including my home phone. The technician's that were dispatched out to repair the cable called instead of coming out. The number they continued to call before coming out was the number they provide service for. (the down phone #) Each time they called and received no answer they listed that call as a missed appointment. I would call back and they would explain that the technician called and no-one was home. When I would tell them I am sitting in my living room, I ended up dropping my home number as the contact and listing my cell number. After doing that they finally called the right phone #. Needless to say I was charged $120.00 for missed appointments. I called at the time of the first billing cycle and spoke with a representative, explaining what had happened and she assured me that I would be credited for that amount. I have called back in July, & August to get this matter resolved and now I'm being told its been 90 days and they cannot issue a credit after 90 days. Pay the $120.00 and they will give me a $15.00 loyalty credit. I realize a $120.00 isn't a lot of money, but I don't feel I should have to pay for their error.
