waiting more than 3 months for my laptop!!!

In October I send m latop (Which I had for 10 months) back to repair after ,all of a sudden it just went dead!! I won the laptop in a lucky draw and received it still sealed and brand new. First they told me that I don not have a guarantee because it was a gift. Then after many phonecalls and tears Joshua Doore agreed to get it fixed. Then after I send it back, 51 days later I finally got my Laptop back, still broken. I took it back to the shop immediately! They eventually got it sent back to the \IT department"and its been over 3 months since I sent it back the first time and I hear absolutely nothing from no one!!!!!! I'm really ****ed off at this stage!!!! They don't even bother to try to keep me updated on the repar of my broken laptop!!! This is outrageous!!!! """
