I Have purchased boat rockerz 255F Bluetooth headset as on Dt- 01.06.19 which has been delivered on dt-02.06.19 . I have face some connection issue as well as sound problem so i have requested to replace as on dt-06.06.19 . Expected delivery date for replacement was dt-08.06.19 but evenafter 08.06.19 they didn't any updation regarding this . I have called many times in customer care executive they just keep saying it will be take five more days to process . After everyday follow up they called me on 12.06.19 and said they should cancel the order and again requested to return they did the same but still there is no any updation . i have never experience such worst service before from any online site . I am really disappointed with flipkart service .They dont have any proper solution .
