Sony India — speaker mhc-v71d

Address:

110007

I had purchased MHC-V71D from Croma Retail South Ex on 19th Aug 2018, Invoice number SLA[protected]. Serial Number of the product is S[protected]D
I had hardly used it for 5-6 hours and it is showing PROTECT3 error. I had called customer care 4 days back and complaint number was 49730106. It was attended today morning and the engineer found some problem in motherboard. I am shocked to see the quality of such an expensive speaker that it got damaged after using for just 5-6 hours. I am expecting not to repair it and get it replaced from company. Need your urgent attention on above matter.
