Worst service ever!!!

Worst service in my life!!! Gave my VW Amarok in on the 12th of march, they gave me a chev spark which was half broken, paid over 100rand in petrol to drive 30kms or so, i was told my car would take 10 to 15days... it is now the 24th of april, im still waiting and now they gave me a chev spark again and i highly doubt its road worthy... im paying insurance, a car payment and i have all the discomfort of this spark for almost 2months now.....
