Third party Avast support experience today left me feeling uneasy

I called the 18443409251 number this morning when I could not get the Avast Secure Browser to work or any browser seemed to have a locked keyboard all it would do is bring up a drop down when I tried to type either customize avast drop down or another so I had no computer access to come here for help. When I tried to do a quick scan with Avast it would not work either. Some things seemed odd to me now. They got access to my computer and a lot of other information over the phone and I was told chromium and other things in extension files they were looking at were bad and my computer would likely stop working if I did not pay more money and add some other things. Today I searched chromium here and it seems to be something avast uses?
One more odd thing after talking to two different people I was asked to end the session and I noticed the time… stated I had been on the phone since 7:41 and they had remote access shortly after that… but the time on the closing popup stated a start time of 8:42 for the first person I talked to and 8:57 for the second person. I now have the creeps… about this entire thing. They asked if anyone else uses my computer I said yes… will not say more about that now but it got creepy and I think they may be doing more than they are telling avast if they are telling them anything… I was told they were in the Philipines but who know not me.
Does this sound ok to you people as it feels wrong.
ps I learned only after coming here and reading about phone assist that it was a third party and not the real avast I was contacting have I been duped? There is more that I will put only in a private message to an avast employee.

I just searched the phone number and got this
Avast Total Care
https://www.avast.com/en-us/total-care

Phone &/or remote-connect support for any computer-related problems.
nothing about third party

Reported to Avast.

how do I report to avast… I sent a pm to a mod here with more information and sent the link to this post… is that enough?

Bob is saying ‘he has reported it to Avast.’

@sandy55,
You also need to realize this is the weekend and it will probably be Mon. at the earliest before
someone gets back to you.

Thanks Bob…
Everyone needs a wkend… no problem there.
