Engineer charge while fault still exists

[Asouthco]

Hi,

I put in a complaint about my speed. Im getting below minimum guaranteed speed, and the complaints case manager sent out 3 engineers to attempt to fix the problem. None of the succeeded and all told me it was likely due to talktalk exchange or something on talktalks end.

I'm still getting under minimum guaranteed speed (90mbps when 110 is minimum on my 150 package) yet I have received a charge saying no fault found.

The fault still exists, I was told by the complaints case manager that I would not be charged as it was clearly a talktalk issue, and yet I've been charged for the final engineer that attended.

Can the charge be removed please? The fault is still present, guaranteed to not be due to anything on my property or equipment from the previous 2 engineers so it HAS to be a talktalk fault, which is still ongoing.

Thank you so much for your time and patience, I have investigated on my end, and the charge is invalid, it will be waived off
