Poor service

My car was booked for normal service 21/08/2015. I requested to check strange noise & car revs & a problem was found with the gearbox. I was told that authorisation from Liquid Capital will be given within a week, which didn't happen. After several phone calls, I mailed Jaco on 11/09/2015 & explained the situation to him. I had an answer 14/09/2015 with a promise of follow-up on where the delay is. E-mail conversation followed on 16/09
