The first time "Patricia" called me and left a msg i called her back within 24 hours just cause that is what i do....i googled it but did know that we had had one issue that was probably going to collection. Ok so no biggie..was going to advise a fair payment plan and move on with life. Guess that wasnt her idea.  the msg i left her was after hours and i was very detailed in my request - could you please tell me what it is regarding and so forth as i work mon - fri 8 to 4 and was not going to call during work. Today was the last straw - she has since phoned back 3 times to which i have called her back twice. Today after 3 phone calls and then one from another number at 1-+1 866-276-2679 (and a recording) saying to call this number back I contacted the ppl i thought was the credit issue and advised i would no longer be dealing with this company; i would not accept calls from them as Patricia completely fabricated a story today that i had never spoken with her and that she didnt know who i was and then she proceeded to hang up on me.  She is rude, disrespectful and there is no way this company should be allowed to have ppl employed who speak to human beings the way they do.  I emailed the ombudsman on the website as well with a complaint. Disgusting behaviour - obviously her parents never taught her how to be polite

they are illegal. Call police immediately.
