Incorrect part / No part

On 23/4/2015 I ordered a part, motor holder on a RM2410 lawnmower at Midas Nelspruit. Due to the pending public holiday Warren advised that the part would only be delivered on 28/4. The part arrived on this day as promised. Even though I provided the model no., unfortunately the incorrect part was supp**** (holder for a 1800w motor was sent). Whilst I waited at the counter, Warren phoned the spares department and reordered the part. I was advised that again due to the public holiday it would only be delivered on 05/5. I received no call on the 5th or in the days that followed and phoned Warren on 08/05 only to be advised that the part had not arrived. He again ordered the part. No phone call was again received and I made a turn at Midas on 12/5 and the part had still not arrived. He tried to phone parts but was unable to get through and spoke to a rep who mentioned that they would overnight the part with a courier. Shortly after this Warren requested that I rather bring the motor and holder in so that they can send it to a service agent. Dropped it off the next day 13/5/2015 and have heard nothing since. Phone today but Warren not in and someone trying to find out for me.
