Unhappy with the incompetence of Spree's agents

Again Spree is giving problems with the return process. I posted my shoes that I wanted a store credit for on the 23rd March confirmed with the Post Office that it was delivered to Cape Town on the 27th March. I have been making numerous calls at my expense to enquire how far the process is and to date no one can give me a constructive answer. The second last person I spoke to said they I would receive an email as I will not be getting a store credit but a refund into my account which was strange because that's not what I opted for, but because she is well trained according to me I accepted what she said, but no email was received nor a courtesy call to at least find out if all is in order. so I called again the guy I spoke said he cant pick up anything he needs to confirm with the warehouse. I am so frustrated no one can actually give me an answer its now the 3rd week and Spree doesn't seem to care. I requested for a another shoe exchange I guess that will also be sorted out in a month's time. I am not happy and someone needs to give me constructive answers and solution, I now want my money back and not a store credit as I will not be doing business with *********** people anymore
