Avast total support giving wrong advice

I am very disappointed with the service I received today through Total Support to which I subscribed today for £129.99.
After a crash of my PC I had Windows 7 completely new installed yesterday by a local technician.
Today I was unable to re-install my Avast Pro Antivirus, so I contacted Avast via phone. The technician communicated via shared screen and managed to install Avast. But he also convinced me that my Windows version was full of errors and I should subscribe to Total Support to “update the motherboard” and cleanup and tune-up Windows.
So I joined.

After 2 hours of “cleaning and tuning up” the then technician didn’t manage to install the 184 outstanding updates.
He told me via chatboard that " the registry got corrupted and couldn’t be fixed."
Also that “he had to restore the computer to the manufacture setting”.

I was shocked as only yesterday Windows 7 had completely be re-installed.
So I told the technician I had to discuss this with my local specialist and finished the remote sharing.

My local chap said this was all nonsense, and how could someone judge that the “registry was corrupted”?
He gave me the advice to try to install the 184 updates in small batches. Which I did.
Everything installed little by little, Windows is up to date now.

I would like to claim my £129 back as I don’t feel I can trust the technical support’s advice.
