Poor quality of the Stereo System

Poor quality of the Stereo System

What i hold is Captur Platine (picked two weeks after its launch). I am okai with this model, but really pissed of with the media system/ instrument comes installed with this vehicle. I almost drove 54k kilometres, drive is comfortable.. but millage is only 15.5 and not 20+ what company claims. All comfort and pleasure spoils just cos of the sterio system (radio: not powerful to pick FM station, Tele call : hv to scream for the other end to hear, which is actually the sad part on the investment, slow Bluetooth) I had reported these issues over email from the 2nd week of the purchase. After lot yells and tug of war the technical head of the service centre (always gave excuses and never a permanent solution) realised and changed the MIC but problem still exist. The worst part is poor response from the team on this issue. Also the fact that most of the time especially on highways I have to park the vehicle to take my call directly over the phone. Still living with Faulty instrument after paying 14-16 lakhs. What a pitty.. My question to all - if the above issues are not reproducible in other capture vehicles except my vehicle does it mean I have to live with the crap.
