Peak Times Infinaty speeds less then IDSN

Question

Yes this is yet ANOTHER post about  the horrific uslessness of the bt fiber team and infinaty team and support in genral.
i hav ebeen having issues since the start of the year really. i have proff dating back almost that far and bt have done nothing to solve the issue  like every one else it seems on the forum they as you to run the  further diags and send the results problem is they HAVE NOT EVER WORKED Further more the times im having problems is  handaly after all the call senders are freaking closed and none one is able to help. some of the results from over this LONG  standing issue.
i might wanna add every time i have talked to a support worker  at bt  and bt wholesale and bt  fiber team i have  folloed everythign they have asked of me including the usless waste of tie powercycling my equitment 15,000 times .
one opperator even insisted  i did it and i was to unplug my phone while on the line to him at this point i refused to deal with him further becuse he clearly had no grasp oh realiaty and could not understand i was on phone talkign to him so unpluging it would just terminate my  support  call that i had  sat in a line for  20 mins, on another  occation some one transfermed me to another team that had gone home and had me sit on a line for 45 mins with no  hope of the line ever being picked up, i confermed this when i called back on another telephone and told them i had been waiting  for this other team for 45 mins and what the hell is going on.
at this point i would rather go back to talk talk boardband it was a slower connection on paper but it worked.
