Useless

I have returned a roland keyboard whereby I received a credit. I then took a midi keyboard as it was what I needed and then also ordered earplugs this all happened in April. I am still waiting on the earplugs and we are now in December. I keep calling and asking but there seems to be a problem with the container every time and they keep asking for my number. I've probably given my number about 20+- times and still when I call they want my number. What do you do with the number?. If you can not get the product I want then give back my money you owe me. Your policy is **** (no cash refund). If you can't get me the product when I need it then what is the use. There are other business out there I'm willing to give my money to.
