False advertising and poor service

So I've been contacting neotel throughout the past week regarding this issue ,i've took on a neotel neoflex data contract on 9/5/2015 and internet is very very slow despite neotel promising fast wireless connectivity DL Rate 3.1Mbps & UL Rate 1.8Mbps .I then tried contacting neotel support and logged the problem via email ,which no one from neotel responded to .After several phone calls and email to neotel support with no one able to help ,but finally after 6 days of logging the,a neotel technical consultant phones me back stating they have made some changes on their side,so i do a speedtest while on the call with him 0.36Mbps DL rate and 0.26Mbps UL rate .So he tells me seeing that i'm getting DL rates of over 0.30Mbps is acceptable by neotel standards and that's all he can do.Before taking on the contract the sales consultant assured me that would receive fairly good speeds based on the fact that i stay about 300 meters away from 1 of neotel's towers.Everytime i phone neotel they ask me to do the same thing over and over again ,but still no results and they refuse to send someone out to sort the problem out .
