My name is alan m alexander owned hyundai creta car 2016 from kollam pothens hyundai. There was a complaint in the stereo and bluetooth and given my vehicle for three days in service centre and finally told that stereo can be replaced in guarantee. From last 3 days i am contacting the customer relationship manager of pothens hyundai kollam but till now he has not attended.
My car stereo system was complaint because of the hyundai road side assistance which your company represntatives tried to start my vehicle after the vechicle is started stereo was not working. After that i had given my vechicle to pothens for the same and they assured of replacement now no response.
