Zebronics — ZEBFIT4220CH-Smart watch issue

Dear team,
I bought ZEBFIT4220CH(Black) smart watch through Amazon on 23.05.2022 bearing (invoice no:MAA[protected] for Rs.3329 and presented as a gift to my husband on our wedding anniversary, but the same was found defective.

Hence I raised complaint at Amazon and got replacement watch on 29.05.2022 Model:ZEBFIT4220CH(black bearing(Invoice no:BLR[protected].

Now after 5 months again the watch is not getting power ON.Hence we submitted the watch at service center which tool 2.30 hours.
Service center has issued a job sheet on 30.11.2022 and stated as the watch will be sent to chennai for repair which will take 5 days to receive.
Finally today we got replacement but the strap colour is GREY which made us very much disappointed with your service and product. I have ordered only black but we received grey strap in the replaced unit which we dont agree /like to use the watch.

This product is very special to my husband on our 0 day but you made us to run behind repeated complaint.we didn't expect such a poor product and service ..

Hence I request you to collect the device from us and refund my invoice value Rs.3329.
This issue made us frustrated and lost trust on the brand and product .since the product got replaced twice we dont believe that that 3rd time replacement will work fine.Customer support is forcing to take replacement of different colour due to stock unavailability which we doesn't accept.we fed up with this product and service, please refund our money and do the needful
