Unstable Internet and Packet Loss (8 Months)

Update:
Had a tech come out who informed me that they were getting this escalated. They had to lay down new lines down my street since the packet loss was so bad and was affecting everyone on my side of the street since I was right in the middle of nodes but were going to have to get approval from the city to get this work done. The same tech, named Steven also informed me that they were going to credit my account $150 this month and once the work had been done on the street laying down new lines they would get back to me and would try to credit my account as much as possible for the 8 months that I had been experiencing issues. Well, I noticed some people with Cox doing some work about 4 trucks the next few days. I spoke to them and they said they were doing as much patch work as they could before the actual replacement of the new lines. Since then I have had pretty good internet and still is running smooth. About a week ago from today there were some other Cox reps out here doing work. I spoke to them and they confirmed they were with Cox. I assumed they were the reps laying down the new lines but was not contacted about any kind of update if the city had approved the work or when I could expect this work to be completed. I had gotten Steven's phone number who told me if I had any questions or wanted any updates that I could call him since he was the one that was going to handle the crediting once the work had been completed. I have tried to call him 3 times and have texted him 3 times as well and have not heard back from him and I know he is dodging my calls since the phone rings only 2 times and goes straight to voicemail.And to add to it I was not credited the $150 I was told I would be this month. My bill came in today and was charged the full amount of $134.00. I am pissed. I will NOT be trusting ANYTHING ANYONE with this company tells me they are going to unless I get it in writing along with their employee number and an email laying out exactly what they tell me they are doing. This company has done nothing but lie to me about everything they tell me they are going to do such as crediting and getting work done. It took 8 months for them to get the right people out her to fix my issue and when it comes to getting a credit they done put it in and hope you will just forget about it. I am now waiting for a supervisor to get back to me about getting a credits I was told I would be getting and to see if they did in fact replace the lines on the street.
