BAD SERVICE FROM POSTNET (STONERIDGE)

I called Postnet (StoneRidge), and spoke to Ashron, after emailing my company logo for design to Gavin. Gavin was not present in the shop, and I asked for his cell numbers. Ashron told me that he will not give out his cell numbers because I am calling for something USELESS. I was offended by this and asked her to apologise. I spoke to Dawid from head office, who said that he will spoke to Gavin ***ner). The owner regard his staff as professional and will not continue with this matter. I called Gavin and he dropped the phone on my ears after saying that he is not interested.
