4th set of technicians on site Now signal gone!!!!

I reported my first signal problem about 6 weeks ago.<br> I have now had 4 sets of Technicians on site.<br> Now I have no signal and the equipment they brought to replace my current equipment is faulty and old. They also did a half ass reinstall of my old equipment with a result of no freaking signal. <br> I want a credit from the time I logged the issue or they must upgrade me to the next speed without charging me. I am really frustrated with the service and the lack of problem solving. As everything was working 100% 2 months ago. <br> If they need to change me to WiMAX that is fine or any other uncapped 4Mb line that works. Just fix the freaking problem and do it fast or come and fetch the equipment. I am also really ****ed off about phoning the call centre as I have probably spent 5 hours talking to them with no success.
