Utterly Disgusting Service Ever!!!!

Utterly disgusting service I have ever encountered in my entire life . For a maximum of 3 mths going on 4 mths now I have spoken to a matter of 5 people including the manager Johan and still to date been trying to get my car serviced and returned back to me. On the 01/12/ 2017 , I left my car there for RAM to complete the check on what was wrong , I received my quote of R61 194..to fix my car , I had to pay a 50% deposit which was made on the 08/12/2017..Since I have made the deposit I have received nothing but excuses from Obvious , then Mark and now finally JOhan ( the Manager) I am continuously calling sometimes up to 7 times to get through and just met by voicemail and calls not returned. To date I have had promises that the car would be ready in January , it is now the 07/03/2018...and still I don't know what is the real problem or f it is fixed or when I will receive my car back. I spoke to Johan ( The Manager ) last week Thursday , who said that he will call me back in 30 minutes... Today I have received nothing and when I call I get told he is not there .. I have now reported them to RMI ... AS i HAVE NO CLUE WHAT OR WHEN WILL I RECEIVE MY CAR BACK , also i am not sure after reading all these complaints with the similar references to my problem , that it will be fixed properly. After R61K ... AND FOUR MONTHS ... I AM SPEECHLESS AND ANGRY AS HELL.. RMI you need to step in and investigate and do something about these people.
