Hi there, i have a question about what to do. But first let me explain the suituation. Just before christmas i bought a Hp laptop for PcWorld for £549, it had a hardware error within the 28 days. I returned it and they said they would replace it there and then, but they had discontinued the model so i could have either had my money back or chosen another model. I chose a Sony Vaio costing £585, i paid the difference, should i have had to? Again within the 28 days i had another hardware error so returned it and asked for a replacement, which they did instantly. Upon getting the laptop home and using it for a few days i was pleased that it was still working but noticed that the model number wasn't the same. They had given me a higher model worth £899. Although my recipt says i have the lower model still. What should i do, i'm delighted to have a hight spec'ed model but then again i don't have the recipt to gaurentee it. If i go in to the store and explain am i entitled to keep this model and for them to produce a gaurentee slip? Or are they entitled to charge me the difference? Any help would be must appriciated
