ISP Reviews by intergrale4x4

As per the title !! I've been a Nildram customer for more than 4 years and was very happy with there service giving me constant 4+Mb speed on a small rural 20CN exchange in Scotland and there customer service was spot on. Next thing I know there taken over by Opal!! The 4+Mb speed drops to 450Kbps overnight!! Bt Openreach have been out checked my line and there's no fault "Router showing connection speed of 6240Kbps" Yes 6.2Mb!!! So I phone Opal customer support "As my Nildram control panel no longer works" And get some bloke called "Qwerseded" That cant understand me, Takes my phone number then tells me that nothing has changed and it must be my fault for the slow connection, Bearing in mind two BT engineers had just left my building and where still packing there van as I was on the phone!! I quoted him the fault code BT had supplied me via email on report and repair of fault, to which he had no answer!! I'm not putting up with this "We buy over a well run company providing a great service then HUMP all the customers" attitude!!! I'm currently drafting my letter to trading standards and will post the results here as soon as I can.
Thanks
