Replacement Broken

Last year in December, I bought an iPad mini from Incredible Connections. <br> <br> In July this year, the battery broke. I took the unit in with original proof of purchase. After many weeks of back and forth, Incredible Connections told me that Core, the suppliers, had replaced my unit. <br> <br> I took the new iPad mini home and charged it. The unit did not become hot, it became scorching. It was almost impossible to hold even after living in a cool room out of its cover for half an hour. <br> <br> I again returned the unit only to be told that after a diagnostic, the unit was not faulty. After insisting that the technician just plug the unit in to charge, it was again 'replaced.' <br> <br> Not only does this replacement overheat, it's battery percentage can be seen to fall wheneve I do anything, viewing a google page for 5 minutes takes 2% of the battery. <br> <br> Both 'replacements' cam rapped in what looks like official Apple plastic, but not in their original box nor with any of the paraphernalia included in an original iPad box. <br> <br> The ware try of my iPad in now weeks from ending, and the attempts at rectifying the problem on Incredible Connections side have been useless.
