Unprofessional repair management of Russel Hobbs microwave oven

I had my Russell Hobbs microwave oven repaired through the Cape Town branch. I took it in end of May. I collected it yesterday (27 July) after some unexplained time delays from the agent and very little feedback regarding the repair process. On collection, when picking the unit up, I could hear something is loose inside. Since it was bubble wrapped, I did not know what was loose. When I got home, I took off the bubble wrap and opened the unit's door but there was nothing visible inside. Since the unit is no longer under warranty and I needed to know what was loose, I removed the outer cover. Lo and behold, the power supply unit was not fixed in place and no fixing *****s visible either. Since I am staying far from Cape Town, I decided to fix it myself and I ended up using my own nuts and *****s to secure the power supply. As far as the general condition of the unit, dirt and clearing wrap glue residue was all over the unit. In fact, the unit was disgustingly filthy and definitely not in the condition that I handed it in for repairs. After cleaning it as much I could, I only then continue to test it for proper working. I am satisfied with the quoted repair but absolutely and completed dissatisfied with the overall management of my microwave.
