NO RESPONSE ON ENQUIRIES

I bought a rose/grey quilt from them more than a year ago. A a few weeks later I received my new catalog indicating that the quilt also had quilted pillowcases together with the quilt. I enquired directly from them saying that I have not received it. Since then only 2 personnel responded on my e-mail, but the last response I got was on 8 May 2015 asking me to provide my ID or account number (which by the way is indicated in the first e-mail). Since then no one responded on my e-mail asking them when can I receive my pillowcases. The account is settled with them think next month but still not received my pillowcases which I paid for!
