Direct Buy Retail

Was at my parents house over xmas and got two calls from this number.  It said Direct Buy of Lancaster, and was obviously a sales call.  The guy was pretty rude from the start.  I asked who was calling and he would not state where he was calling from or why he was calling.  I asked to speak to a supervisor and the guy hung up, then he called back right away.  I was not as polite this time.  He said that he was the supervisor and that "he most certainly would" call back because my mom called him.  He even started to provide a certain time and date.  I seriously doubt this because both of my parents are at work during this time of day.  Not sure what they were trying to sell, but it seemed pretty shady to me.

They are really annoying...I too had the same experience with rude sales people trying to tell me I contacted them.  They call several times in a day and never leave a message.  Sometimes if I answer which is rare, no one answers on the other end.

keeps calling with no answer. happend 4-5 times a day.

Today is 1/29/10, they have been calling nearly every day since 12/15/09 sometime 3-4 times a day.  I've never answered the call, and they have only ever left one message.  Very persistent, very annoying-I'll never go there.  Anyone know how I can block the number from my cell phone?
