Ibreak refuse to refund my R15000 paid to them..

My Macbook's motherboard broke. I then contacted them and they quoted R12850 for a new one. I iterated that is must have the same cpu /ram etc as i am running lots of virtual machines, the technician assured me it will be identical. I thought as i am doing this i might as well replace the battery which took the cost up to just over R15000.00. The gave it back to me with half the amount of ram. The battery was worse than the one i had because it has been standing since 2012. (li-ion) complete discharge is an issue.After taking back they kept on telling me a new one was on order which was a lie as the technician eventually admitted they would have to take one out of another machine months later. I then said fine take the battery and the motherboard out and refund me.<br> They keep on saying they will do it and never refund it. This was from Nick Barnes on the 9th of December.<br> \Apologies for the delay<br> Our suppliers have passed a credit and everything is in order
