DSL Internet service

Same problem in Coolidge TX. For 3 weeks now DSL has gotten slow from roughly noon to midnight. Local tech says the problem is on other end at little rock where the DSL runs out of. I get 12mbs plus sometime after midnight till noon or so then the drop off starts till by 5 or 6 it stops completely for seconds at a time or drops to .50 mbs or less. Its 10:45 pm now and it is running at 44 ping up .63 & down at 1.24
