Poor workmanship and Delayed Delivery

My vehicle was booked in for repairs at HiSpeed by Outsurance. Vehicle was delivered there early Jan 2015 and after more than 7 weeks I was dubiously conned into accepting partially completed work with a promise from Johan that the outstanding work would be completed ASAP when the parts on back-order are available. It was also agreed that the additional damages caused during the time the vehicle was under their control and safekeeping would be remedied, and that the pirate parts would be replaced with correct approved items. Outsurance had to intervene because HiSpeed \paid themselves"via a computerised payment system. We eventually managed to get them to take the vehicle in for the obligated repairs & completions on 20 April. Johan committed to have the vehicle finished & ready for collection on 25 Apr. Today 25 May"
