returning goods

<p>So i went to Mr Price Westwood mall on the 25th of November and bought a few goods there. when paying with my debit card they told me 3 times it was declining so i ended up withdrawing cash. While withdrawing i recieved an sms stating that the payment had gone through from my account. I went back to the store and showed them my sms and they double checked and said that the system confirms the transaction to have gone through so i took my goods and didnt get a slip because it didnt print for whatever reason. A few days later i went back i went to return the goods as they were damaged and asked for my money back but because i didnt have the slip they couldnt give me my money and iwas told that the transaction cannot be picked up from their system. They asked me to get a bank statement showing that the money was never credited in my account which i did but before that they have promised to call me and still nothing. i tried calling the store and no one is answering. so now i want to return everything that i have bought as i no longer have any desire of shopping with them. so i have no goods, no money returned and no apology or even assurance that this matter will be resolved. What kind of service is this. Their system error has become my problem. I want my money back or else i am taking this matter further</p>
