Pathetic Mechanical Warranty/You're Wasting Your Money On This Forgotten Brand!!!

I used to be a proud driver of Mercedes Benz however their service & commitment to their customers, especially premium customers, has reached a pathetic level. After seeing the many single star reviews on Mercedes South Africa I am wondering if the heavy weights up in Germany have given on their brand in South Africa? I recently purchased 2 luxury Mercedes Benz models, A 2022 S400 & a 2022 G63. I have had endless hassles with mechanical faults on both these vehicles & the staff at Merc The Glen & Merc PMB have no concern in after sales service. Its been 6 months of back & forth to get my issues sorted out with no Joy whatsoever...It took them almost 7 months to sort out my S400 & its been 7 months that I am waiting for my G63 to be fixed. We pay premium money for backdoor service & it is now becoming clear that Merc SA has no concern over their customers & are just in our country to skin us for all that we have & leave us hopeless with a defective product.
