KIA Paarden Eiland Disgusting!!!

I've had a KIA Rio since 2014 and been doing my service with the Paarden Eiland branch for the past 2 years. I scheduled my service for past Monday 23 October 2018 and they called to say I need to have my wheel bearings replaced at a cost of R4400. Being a woman and trusting the service provider I was a bit shocked but assumed that this was the cost. My fiancé advised I get more quotes and ACD Bellville quoted R1500 for the same job!!! I was so disgusted and when calling them out on it - they said they can reduce the cost to R3800 for doing the front wheel bearings. I declined. Whilst I understand that these outlets sometimes charge more - I think this is a complete ******* and simply disgusting. They know as women we don't know prices - but this type of business is just ************!!!! I definitely won't be going back and it's sad because they have tarnished the KIA brand as a whole for me.
