PATHETIC SERVICE

I CANNOT STRESS ENOUGH HOW PATHETIC THIS SERVICE IS, AFTER VARIOUS CALLS AND 6 WEEKS LATER, MY ISSUES ARE NOT RESOLVED, I KEEP ON PHONING, THEY LOG TICETS, WITHOUT HAVING ANY PROBLEM SOLVED, THEY CLOSE THE TICKETS??? I AM PAYING FOR A 200MB LINE, BUT ONLY GETTING HALF THE SPEED? HOW LONG CAN IT TAKE TO GIVE ME A SOLUTION?????
