LACK OF SERVICE

Just over a month of having metrofibre and with constant issues, speed, range and signal. I have called in numerous times to try and get an answer. I am now told that METROFIBRE can not guarantee their signal, range or speed, however when I called through to activate my metrofibre the sales man on the other side told me he had to check what was available in my area. He then told me that I am able to get an 85mps line up and down. So I app**** for it. I am only getting speeds that range from 5mps to maybe 45mbs. (this has been tested with my phone - mobile data off) if Im in a room not even 5 meters away it drops to below 5mps. I am now told that I need to get a lan cable and plug it in to do a lan cable check, however none of my devices have the faciltiy for the LAN cable so now metrofibre are telling me that I have to go purchse a USB RJ-45 LAN adaptor to do the test for them. I live in a small town the town I am in probably wont have this. So that means I have to drive 30kms to go buy this divice. this is not fair and having no support from managers this seems to be on going. PLEASE CAN SOMEONE HELP ME FROM METROFIBRE. I spoke to a lady yestserday who told me she would escalets this to a manager, however this was not done.
