5weeks still no resolve to my problem

Jan 2015 bought a Acer laptop from them. Jan 2016 it started giving problems not starting up completely!!!<br> Still under warranty, since i took out an extended warranty, I managed to get it to them on 6 Feb 2016!!!<br> Two weeks later I had to call them to find out what is happening?!? Only in the third week they came back to me saying the motherboard and screen needs to be replaced costing R14000...<br> Now a further 2 weeks later, no laptop for me... Their head office apparently wants to decide whether a new laptop would be better(less cost for them) or if mine should be repaired as mentioned!!!<br> In total I have been without a laptop for 5 weeks, another few on the way as its currently going...<br> This is unacceptable!!!<br> <br> I was offered a loan unit yesterday, but the loan contract states that i am solely responsible for this loan unit!!! If ****** i will have to pay/not get back my own laptop!!! That means i will have to take out aditional insurance for this loan unit, more costs being incurred on my side!<br> <br> I have already spent R1500 on calls and travel(Queenstown to East London) to try and resolve this issue!!! Calls dont work so face2face was next and does not seem to work either!!! Plz hel
