Postnet Calling me a *********

I went to Postnet Canal Walk branch to have 2 photocopies made and asked if the documents could be certified. The attended said he would not as one of the documents to him was already a photocopy. Basically I was called a ********* right there and then. The document was printed and stamped and dated by my bank. I then requested the manager who took a look at the document and said he would copy and certify even though it is a copy. They were blatantly rude and labeling me a ********* and untruthful. I am a professional person and I find it utterly shocking that I could be treated so rudely and disrespectfully at this branch. I would have gone elsewhere but I had time constraints and didn not want to leave Canal Walk and go elsewhere. I don't know how they think they can speak to customers like that. I will never use their services again and I will let others know about this. I do not recommend them at all and demand an apology. I will go as far as to prove those documents are originals.
