I received my order of Portronics harmonics neckband on 28 may 2022 but the product is not good and has fault .Next day i called on the official number of bajao to return my product but the call is not placed .after many calls they received and said that it will take time and i mailed after a week because there is no response from their side. They are making excuses whenever i called and they forward my call but not returning my money.Please solve my problem as soon as possible.
