Cash Crusaders - not willing to accommodate a customer

I bought a 2nd hand laptop from the above mentioned store and after almost 4 weeks the laptop completely died. It wouldn't charge and wouldn't turn on. I returned it to the store and it was sent for repairs and only after numerous queries from myself I was eventually informed that it could not be repaired. I was offered a replacement laptop with a smaller HDD which I agreed to provided all my important information/data be transferred from the original drive. Again no.word from them for days and when I queried it I was informed that the replacement also had a problem so now I must get a more expensive one and pay the difference in...quite ridiculous, I am already losing out financially while I do not have the laptop, I urgently need my data off that hard drive and they are not willing to resolve a customers issue and provide a replacement (whether they have to take a knock or not, that is not my problem).

I am not getting any joy from them here and they are not willing to budge and I will be reporting it to the CPA...
