Above are the details and for each time i have to submit my cell phone for 10 to 15 days in service center. For gyroscopic sensor problem when i visited service center they told me that there is a mother board problem so need to change your mother board at the coast of 9000 inr, but as soon as i told them that my cell phone is under warranty period they suddenly change their tone and told me that this problem will be resolved only after updation of software. Motorola company has given me the faulty instrument. Last time i called on motorola customer care number and demanded for the replacement of my instrument but they deny to do so (Reference complaint no.:[protected].in the warranty period of just 10 month i had to submit my phone for 5 times and now my warranty period is about to expired in january – 2018. So i request you to help me in this matter. Please guide me what to do now.
Moreover i am using motorola product since the time of moto flip. Apart from this i have motorola cell phones i. E. Moto g2, moto e2, moto g5 plus & moto g3 turbo. I can submit all these cell phones with bill to prove my self trust worthy, i had never such bad experience in the past but this moto g4 plus is faulty instrument so i want it to be replaced only. Do needful as soon as possible.
This is the height of tolerance, today a week has been completed and still i am not getting any solution about my cell phone, when will i get my faulty and damaged instrument's replacement???
Even they are not interested in replying back to my emails.
