Plano glass Cussed at me on the phone plano Texas

I called Plano Glass on March 3rd.  I was speaking with Collin trying to get some help with an up coming project.  Collin was getting very inpatient with me because I wasn't understanding.  I needed more explanation of some idea's and Collin was very unprofessional and told me to, "GO f**k MYSELF" and call someone else.  I will never call PLANO GLASS again for help.  They have Collin working there who shouldn't be answering the phones.  Becareful fellow people that need help with glass questions, don't call PLANO GLASS UNLESS YOU WANT TO BE CUSSED AT!
