My parents was on 40/10 always got stable with 37/9 for the last 2 years with line rental and anytime call plan. They decided to renewal with Fibre £25.99 per month (24 months contract) but removed line rental and lose phone number on May 14th. The engineer arrived swapped over to SoGEA 80/20 but VDSL was very poor speed struggling with 37/8. Plusnet send out engineer for Friday, 31st May - Engineer named Mike and he spend almost 2 hours and then came back saying sorry the speed is slow due to very old green cabinet not coping with it and say he will be back in three weeks time to fix this issues out but plusnet not happy with it and arranged another engineer this time booked for Monday, 3rd June and this time the engineer named Thomas and he found network fault outside down the street with broken cable as he will replaced it and he took nearly 3 hours then resetted DLM on his remote kit and the fault was fixed. The speed now went back to 72/20. It's appear the first engineer was too lazy can't be arsed bother to fit it. Thomas say the reason for slow speed on 80/20 as the test come back fault on the voice line, disabled it and fixed other damaged cable and resetted DLM. The test kit came back pass on his remote kit. He also told my parents their area are expecting to have full fibre soon possible next year.
Good job I spotted it for my parents otherwise they are waste their money for 37/8 on the 80/20 product if it wasn't for me.
