TV problems

We returned to Rhode Island on 5-28-25. On 5-29-25 we started having issues with the guide, it keep going up and down really fast and we had no voice command so we called Cox. On 5-31-25 2 people arrived and they were here for a long time and appeared to fix everything. They shut the TV off and left. Within about 1/2 hour we tried to turn the TV on but it would not work. We tried all 3 TV's and none of them worked. We called Cox and they said they would try and get the repair team back there before 7PM but if they didn't come back then we would be on a wait list for Sunday 6-1-25. We waited and they never came back. Another day with no TV. On Sunday morning we called to confirm we were on a wait list and the individual said no, they had no record of us being on any list. They put us on the 3-5 time slot appointment list. We informed them that we had an appointment about 10 minutes from our house and we should be back around 3 but could the repair person call us when they were on the way. No problem was the response, they will call. Around 3:05 our Ring doorbell indicated that someone was at the door. We tried to communicate with him but he left. We called Cox and they said they would try and get him right back to the house. We arrived home at 3:10. We waited and called at 4PM and Cox said that he came back home at 3:45, no one home, and he left a door hangar. There was no door hangar, we were home and we checked Ring doorbell and no one was there. He also did not call. We called back and they now say that it is up to the driver if they want to call or not. New appointment for Monday 6-2-25. Still no TV. The repair person showed up Monday was very knowledgeable and fixed everything. On Tuesday 6-3-25 we turned the TV on and it did not work, none of them. Called Cox and now waiting until Thursday 6-5-25 for another repair person. Once on Sunday we called and got a girl in another country that was not helpful, put us on hold for 15 minutes and then hung up. We need help and to date nothing has worked. What do we do next?? There is more to this story but we just want the TV's repaired.
