Be aware of being ripped off

my grand cherokee had just gone over 100 000km and i took it in for a repair on the radiator, everything else was fine at the time. i got it back and despite feeling that i had overpaid for the radiator repair (R16 000) felt assured that it was done correctly. on getting into the car however i noticed that the suspension was totally flat and felt like the air had been let out of the bags (which it had) it was very low and bumpy.. in addition to this the pdc was also suddenly faulty. i took it back and asked them to pls check as it was fine and i was sure that the error would not show up on the computer as i was sure it was working when i took it there.. they simply reverted with a quotation of R45 000 for a new air pump.. i was extremely upset about this as i was certain that the car was not like this when i took it to them, after begging and pleading and making them recheck the fauly (at this point through my partner as i could not talk to them and remain calm anymore, knowing that something was strange ) they agreed to lower the price to R38000.. this was still however too much for me to get my head around so i put my feelers out and was refereed to American SUV in centurion and left the car there with instruction to please "check the suspension" as computer said it needed service. they gave excellent service and i was called back later that same day with the question "what is the history of this car" i explained the issue that i was experiencing and was told "that is no surprise, is your pdc also not working? " to which i said yes, how do you know..? he then explained that the plug for the pdc and the pump look very similar and that they had been switched around ie pump into pdc and pdc into pump rendering both useless.. it cost me R5000 odd for that but its a hell of a lot better than being robbed R45 000 by who obviously switched he plugs around as they were the ONLY ones to ever work on that car.. THIEVES! i love JEEP btw, its my second, ill get another too but do yourself a favour and forget about jeep fourways..
