Address:

puthumangalathu,kuzhithura(po),karunagappally, 690542

When i visited reliance trends karaunagappally on 8/10/2019, there is no one to attend me (customer), and they were busy with some other works. They don't care about custoemrs and they are very slow with billing.we brought 13000 rupees purchase. And i ask for complaint registration and they customer feedback log, then i ask for service manager and he is not in the shop, he ask me to visit again then he can solve the problem
