Speed dropping since contract renewal

[niteninja1]

I pay for 150mb down.

was getting 120mb (so happy enough) down for around 18mnths

contract renewed and my speeds dropped to around 70mb down.

eventually had a openreach engineer come out who confirmed it was not a issue in the property and then reset the line at the cabinet which fixed it.

a month or so later speed dropped again.

spoke to someone on chat who after a hour or so managed to reset something on their end (i had to go into a lot of detail that the engineer confirmed it wasnt a issue in my property) which fixed it for another month or so.

problem has came back again. support insist on sending a engineer. Although both times ive booked apparently there has beena  technical issue and the appointment never went through. 
In the latest case they even confirmed on the day that the engineer was on the way and only moved from that statement after the arrival window ended.

OK thanks. To investigate further we will need to arrange another engineer visit. If you'd like us to do this please let us know and we'll confirm some details with you

I’ve never actually had a landline phone plugged in and don’t own one.

i can say i very rarely see and drop outs with my broadband (as in I’ve had my 2 outages since moving here)

Thanks for that. Line test is passing but I can see that the sync speed is low. Are you experiencing any problems with your telephone service, any noise on the line?

Yep. Ive tried:

Ive done the 30mins reset steps.

replacing the router (i have a gfast modem) and running the speedtest on the router. Ive tried new ethernet cables.

as i say the openreach engineer has confirmed nothing within the property is the issue. It seems to be talktalk/openreach throttling the speeds as they can reset something on their end that fixes it.

i can directly tie the issues starting to the contract renewal time (i also note my minimum guaranteed download speed went from 120mb to 100mb)

Have you tried turning the ONT off for at least 30 mins? If still slow, not knowing the make/model of the router that you are using, can you connect a wired device to the ONT in place of the router & do a speed test from there?
