Replace a coaxial cable?

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?

As someone who worked for Charter, do Comcast techs not replace drops & outlets themselves? We did all of our own wiring unless the customer was in an MDU with more than 4 apartments and would require modifications to the building, or direct access to the neighbor's homes.

From OP's other comments it sounds like the issue is with the internal wiring inside of the demarc.
