Terrible terrible customer service!!!!!!!!

I have placed an order the 11/05/2020. I have not received my order since then. On Monday I phoned to find out what is going on with my package, they told me that some of my things are not in stock anymore but they where waiting for me to phone to tell me this. So I requested a full refund on Monday and so for I have no received any concrete feedback. I spoke to Brandon he said he will call me back but he did not. I tried calling back I few times but they just keep putting the phone down in my ear. I just want to know when the refund will be done!!!!!!!!!!!
