Incompetency end-to-end

Worst service ever, it's 11:39 the technician is still fitting a device on my car since 08:00 and their scheduling department team lead won't take calls unless they know what the customer wants, this is after Sibusiso from their scheduling line hung up on me cause it was knock off time yesterday. I am paying for pure incompetency throughout the organisation since nobody can't do anything right.
