Worst service in my life.

I purchased a Bosch Angle grinder at Makro on the 28 July 2019 for R640. By the 20th October it was giving us problems, so we had taken it to Makro Returns because it is under one year warranty, Makro advised that they will send it to Bosch to see what the problem was. When we returned to Makro they advised that we had to pay R453 to repair the angle grinder, because Bosch advised them that the warranty does not cover everything in the angle grinder. We then advised Makro to please return the angle grinder back to us. When we went to pick it up from Makro it was in a plastic bag disassembled, and if we want it put back together we have to pay Bosch to reassemble it. What nonsense is that? What kind of service ? The same angle grinder in going for R499 in Makro but they wanted us to pay R453 to repair it does it makes sense. They was a guy by the name of Ivan that called me was of no help either he just spoke the same bull**** as the people in Makro.
