False promises, disappointing service... no decency to return calls...

Bought CarPlay software at a cost of R4500.00 for my Scirocco on 4 January 2018. Despite VIN numbers and all those details, dealership discovers that the Scirocco does not have an Apple compatible USB AFTER the install. (Only Android.) No stress... a cable can apparently be made up for about R400.00 I am told... 2 weeks later I get a quote of R1780.00 but dealership will throw in the labour for “free.” Mid March my cable arrives... but now has the wrong USB connection so cannot be fitted. Get my car back, but now my old USB port no longer works! Mid April I get told the correct cable is on track for End April. It is now 3 May and I cannot get hold of Dwayne who is apparently “assisting me.” I have officially been waiting 5 months for a cable from Volkswagen!!! Where ever have you experienced ‘customer service’ where 3 days later and multiple messages left you still wait for your phone call to be returned! False promises, disgusting and disappointing service! As long as the sale is made I suppose?
