Boat — boat rockerz 255 not working

Address:

Kolkata, West Bengal, 700063

I have already submitted all the reqd doccument and registered a complain long back but the service team has shown me no response please look into the matter asap. I have also submitted the invoice bill from amazon and they denied it to be the required invoice and told me to submit the correct invoice but did not inform me how to find the correct invoice.. I have tried to contact their helpline no multiple times almost through a week.. But nobody spoke to me and assured me that they will get back to me in 48hrs.. But they never called me back.. This kind o[censored]nprofessional behavior is not accepted from the boat organisation.. I request you to help me out as my warranty period is getting over in the next 1 month
