Rude and non existent service

I dropped my car at multifranchise stikland on Thursday morning, after I noticed that my fuel tank was leaking after I filled my car up with petrol. Roche Badenhorst signed it in - no feedback from them after 4.30 that day, after I called several times - no feedback on Friday - my car has been kept whole long weekend. Emailed Roche, Jonathan Sampson, shillton and dealer principle Eugene du Plessis - nobody bothered to respond until 1.30pm today after several emails - still no feedback from Chery SA with regards to the warranty which is valid for 5 years and no definite answer as to when fuel tank will be delivered. As to my petrol that has been leaking since Thursday, goodness alone knows what is happening there as I also don't get response to that question. I cannot believe the ****, non existent service I have received from this service center and not only now but for the past 3 years - on every annual service due - such attitudes from the service advisors, charged me for wheel alignment that was never done, as I marked my wheels to see if wheel rotation had been done before balancing and alignment - ******* on top of **** service!!!!!! I will never recommend them to anybody and people should stop going there and buying cars from imperial I will be never make that mistake ever again!!!!!
