Very bad service

Iso Computers city is a clothing making company and is giving false adverti*****t. They also do not give a professional product. I asked if their grey Tshirts are 100% cotton and they said yes. When I got the shirts it was 60% cotton and 40% polyester. After I asked them about it they said that anything containing cotton material is to be considered 100% cotton. Then she said google it. Then I googled it and found that 95% cotton materials are to be considered 100% cotton. So even after she said google it I showed her and still she just she well we will not refund you. They are not helpfull or professional. My branded shirts where also printed in the wrong place according to the mockup images I sent them. Not happy with their work at all.
