Preston Harris should be avoided!

Very unprofessional.  Caller was Preston from Grand Energy.  Would not take "no" for an answer then insulted me by saying I was unprofessional by not wanting to continue his call.

This [***] called earlier this week asking for the owner of the company, butchering his name in the process.  All calls like that get sent to his assistant.  He proceeded to piss her off royally so she hung up on him.  He called back a minute later and asked for the owner again so I transferred it to her again.  When she picked up he had the gall to say, "You didn't just hang up on me, did you?"  She told him she had and hung up on him again.  I've never seen her that mad at anyone trying to peddle anything and she actually came and told me the next time he calls to hang up on him!  So when he called again today, that's exactly what I did!

Preston Harris of Grand Companies called and said he was following up on a previous conversation he had with the owner. Owner says he never spoke with this guy in the first place. Gave a different call back number than the one he called from (214)384-4525. researched both numbers and Grand Energy kept coming up for this number. Also known as Grand Operating, Inc. Does he not know what his company's name is? Probably looking for investors.

I unfortunately picked up a call from Preston at the 972 number, thinking it was from someone else. Started his pitch & I said no thanks & he had the hutspa to demand why NO.  I hung up at that point....he tried calling again from 972, then tried again 3 times from 214-384-4525.  Persistent fellow.
