Bad service

Our Toyota fortuner was taken in on Tuesday morning and we were told it would take 2 days to sort out the problem that it had been taken for... 2 days been Tuesday and Wednesday then we called on Thursday only to be told that the parts will be there soon and vehicle will be done by Friday its now Friday and when we called to check on the vehicle we were told that the parts will only be coming in on Monday. This has caused a huge inconvenience as that is our only vehicle which we use for our business as well as to pick n drop my kids off at creche. The staff at the branch are off no help when u call in. I'm so disappointed and angry a week prior to this when the van went for the service we were told we need to pay cash as it was not covered and I insisted they have an extended warranty as well as a service plan but somehow this info was not on their system only until we were not willing to pay and decided not to have the parts repaired then suddenly their system found our information. Every time the van went in for a service there is some issue
