Cox reps locking more threads

I had one rep try to tell me that it was my computer was most likley infected with viruses and tried to sell me on a support plan. I told him I do IT for a living and hes trying to scam me and he DC the chat. I have had 2 field techs come out each said that the problem is with the node down the street. The node crews have been out 3x between me and my neighbors calling and nothing has been fixed. The Internet is almost unusable most of the day. This has been going on for 5 weeks, and the most cox wants to do is send a field tech back out to the house... and the cycle repeats.
