lack of customer service by kia kenilworth

this is my 2nd if not 3rd complaint since I bought my kia rio in November 2015. my last recent complaint was with my spare key and was only resolved after pushing and fighting them and until I wrote to hello peter. on Tuesday, I took my car in for service and they had to change the front wheel bearing which I don't understand why a "new" car would have such problems so prematurely. they never call to update me instead I follow up like they doing me a favour. no one wants to take accountability and responsibility, no one wants to commit, no one can tell me their turn around time until i discovered that kia centurion did their part and just waiting for kia Kenilworth to send them proof of payment. my kids have been off school since i took the car in and they don't even want to listen when i suggest a curtsey car. im dissatisfied with this kind of customer service and i demand answers. i need that car released before end business TODAY 05/05/2016.
