Leeco — after sale warranty repair issues

Hi, i have purchased leeco mobile in nov 2016. Exactly after 6months it stopped working and i had gone to service center in borivali west they have checked it and informed motherboard problem and needs to be surrendered for repair i have submitted my phone on 3rd june and they informed with in 15days i will get back my phone. It has been more than 2months still they are informing they are waiting for parts from leeco. When i call leeco customer care each time they are informing in next 10days they will deliver the same. It's keep going with out any progress.

Appreciate your intervention on leeco please.

Thanks,
