I've been getting crazy calls from telemarketers for 2 days, so when I just got this one and asked to please stop calling they have the wrong number and to take me off the calling list, the (nasty) man turned around and said ok we'll be calling you every 5 minutes...and he hung up and called me every 30 seconds for about 2 minutes.

Got a call too. Didn't answer. No voicemail left.

Got a call from them, the rep started cursing when i ask to be removed from calling list then repeated to call back for 3 mins

Do a search on call blocking devices and phones.If its a cell phone, there are free call blocking apps out there including trac & straight talk.

I received a call from this number stating he was calling from RCI AND INTERVAL INTERNATIONAL. When I asked him to take me off his list - he became rude and began making degrading comments. When I hung up, he continued to call back.  This is harassment
