Still awaiting a promised refund

Hi I brought my phone with a badly cracked screen in, last year September to be replaced and the phone was there for a long while and the screen was not repaired correctly and wasn't a original as quoted and paid R2200 as well as the side panel and buttons being replaced with plastic ones not the original metal and not even the same color. I had to move back to Gauteng and was told to mail the phone back which it did and weeks later after being promised the phone works it was sent to George because I was getting married. Yet still the same issue and phone is faulty and doesn't work. I contacted you guys to give me a refund and you wanted the screen in return and I explained I cannot send the phone back as I am leaving for overseas as explained weeks/months prior and that I am certain the old cracked screen can not go back on as it was kaput. I was promised a refund would take place within a month. Yet nothing ever came and now you blocked me. Soy question is where is the long awaited refund?
