Appalling service at N1 Branch

We are receiving ridiculous service from Cartime at N1 City Cape Town. Our vehicle has been there since 11 November and today is 16 February, that is 3 months. We are receiving empty promises and the same story over and over from the mechanic who at this point sounds like a broken record. We have even been contacted by Jacky who we belive is the area manager who was rather blasé about everything. We get barely any communication about the progress and when we do it is a joke as they will state what they are doing that day and then days later when WE follow up we find out they haven't done what they said they would. We are spending a ton of money on this vehicle yet having to wait literal months. Today again we were promised we would have our vehicle and surprise surprise we don't. We have been taking our vehicles there for the past 2 years for all our services and when we experience problems with our vehicles and have been recommending friends and colleagues. This experience has been absolutely appalling making us not want to take our vehicles back again. The customer service received from some staff is also a joke. Highly disappointed and highly upset. We have had to deal with numerous phone calls and have been to the workshop on multiple occasions whereby we are never able to escalate the matter as there is never a manager or senior person on site.
