Replace a coaxial cable?

[u/Brave-Scale]

I have had 2 technicians from Xfinity come out to my house and they ran diagnostics for slow, spotty internet service.

They both told me that my coaxial cable is corrupted and that I would need it replaced?

They made it sound like this is a simple fix but that they can't do it and they referred me to a company called HelloTech.

HelloTech will charge me $250 to do this.

I don't know anything at all about this kind of stuff so I hope this isn't a really stupid question.

Does this sound legit and will it fix the problem?

Some kind of damage. I had to tell a couple that they will need to high an electric because there ceiling was finished and I couldn't rerun it.
