BAD SIGNAL/SERVICE

I HAVE COMPLAINED ABOUT THIS BEFORE, AFTER THAT COMPLAINT THE SERVICE IMPROVED FOR ABOUT THREE WEEKS. NOW BACK TO THE SAME!<br> FOR THE PAST WEEK MY INTERNET SIGNAL HAS BEEN VERY WEAK. AT TIMES TAKING AROUND 5 MINUTES TO LOAD A PAGE. FREQUENTLY I GET A MESSAGE SAYING CAN'T FIND DNS SERVER.<br> <br> I AM PAYING FOR A SERVICE WHICH I FEEL I AM NOT RECEIVING! MY DATA THAT I NOW CAN'T USE WILL BE LOST THROUGH NO FAULT OF MINE!<br> I WANT THIS SORTED OUT PROPERLY ONCE AND FOR ALL!!!!!
