Unreliablexservice by MCR

This business located in Trichardt Mpumalanga promised to have my csrcreoaired by 9 April. Then they promised it would be finished this week. Now they tell me it will only be finished by 30 April. I have already planned my holiday in the Eastetn Cape for which I will need this car. A Haval H1. In the meantime I am sitting with payments on a rent to buy vehicle to the tune R6000 a month and I had already arranged to return this vehicle this week by Friday. This is totally unacceptable.
