Frustrated/ Tired/ Flat Broke

I wrote a previous complaint last week regarding a simple refund request. The 19th got a sms asking me again for the proof of payment which by now I have sent maybe 10 times! Again I sent it via my bank and also faxed it from my work. Today I wanted to follow up as I literally have NO MONEY left. Spoke to a lady and guess what they are still waiting for the proof of payment. I couldn't finish the conversation as I was too emotional and started crying as I am officially now fed up! What the hell???? When can I get my money back I spoke to how many people confirming that they got my payment and the proof. Please this is getting ridiculous it is the 23rd today. I reported this on the 5th already!!! I want feedback ASAP.
