Disgusting service, Lies,not taking responsibility

We bough a laptop from this store and within 30 days the laptop was returned because it didn't charge. Lenovo admitted that the charger was faulty and replaced it. 4 months later it had the same problem and Lenovo admitted that it still had the same problem as before. Makro, however, said the cover had a crack and it was faulty because we must have dropped it. They sent us photos of the crack, which we were fully aware of. Next thing, we get photos from Lenovo showing extensive damage on the cover that wasn't there before and didn't show on the photos Makro took when it was handed in. They received it like that which means that the laptop was dropped and damaged at MAKRO, who refused to take responsibility and only offered to pay 50% of the repair costs. It has now been nearly 2 months and we still don't have the laptop back. We've explained how urgently we need it back but they don't care. This morning it was confirmed that the laptop was received yesterday afternoon and said we could collect. No surprise, when we arrived it wasn't there. They keep lying to us and do not care how much they inconvenience us or the cost that we had to carry because of their lack of service.
