Need to repair my Tribit Bluetooth speaker, kindly suggest good shops in Kochi

Recently my Tribit Stormbox 2 speaker stopped working. Despite showing the charging icon when plugged in it doesn't turn on. The speaker sounds really really good for the budget and I don't want to throw it. I'm planning to get this repaired but I don't know any good shops in Kochi for Bluetooth speaker repairs. It would be great if someone could suggest some good shops.
