Bad service

Bad service waiting longer then a month for a responds from them on helping me on my internet that they said they will switch from 1 tower to another. What does it help if they say you are fully covered in your area when you get it they say sorry for the bad line they will sort it out. Have this problem from day 1. W I get less then 1mb per second where I have a 10mb lane it takes me almost 3 days to download something I can't play online games at all and my streaming videos or Netflix I can only do sometimes. I have my internet more then 4 months
