Boat — Poor quality boat headphone

Address:

plot no.F/709 cda sec-7, cuttack, odisha

Recently i purchased boat rockerz370 wireless headphone which cost me over 800, its not been a month i started facing some problem in the slider or we can say the extender.
it was jamed or feels something got stucked inside there. Yesterday i usually extend it and as always it was jamed then i tried and finaly it broked, even i wasn't putting that much forcce on it..
then i noticed the improper wire connectivity caused all the problem, which goes under the technical issues.
plzz help me, repalce it as much as possible.
