Worst Service and horrible treatment

It is shocking to see the type of service provided from this company - My vehicle has been with this supplier since 27 November 2019. I can not tell you how many calls i have made to this company where i had been holding some times for over 30 minutes to speak to someone as they NEVER EVER call you back. My service consultant Patricia is the worst customer care agent that i have ever come across - In all the times i have requested her to call me back she has not once called me back - Even her manager Lana Abrahams has promised that Patricia will call back has never done so - Even Lana Abrahams has promised to call me back and has also never done so. I have left messages for Tony the workshop manager to call back - Its been a week and 2 days already never has he called back - I even reached out to the owner Gabriel Naidoo who has also not contacted me. The fact is that when i call to follow up on my vehicle they are still awaiting parts - which is shocking, i asked for a courtesy car - Which i was initially told they do not do courtesy cars - after i was in tears and begged for help I have been promised a courtesy car - which has also not materialized as everyday there is a new excuse as to why i can not have one. each time i speak to someone as i am insisting to hold for someone to help me they answer but are so rude to me and treat me like im an idiot all i ask for is assistance in my matter or atleast my vehicle back so i can take it elsewhere
