want to knoe who this is

Who called me from this number?

This is from a company that tries to sell you vacations or buy your timeshare.

This is RCI points calling - with the purchase of RCI by Wyndham they are getting more aggressive in renting time deposited by the real owners ... which is why you can't find trades when you try to redeem your points.  Refuse to work with them.  Keep control of your time and use it or trade it yourself.

If I am on the opt out list, why do i keep getting calls like this on my cell phone. what else can be done to stop it.

Maybe should come up with some kind af class action suite against these callers.
