Boat — False promises from boat team

I had registered replacement request on boat lifestyle website as rockerz 295 v2 I bought its one side stop working after only 2 months..they accepted replacement request and rockerz 295 v2 I send recieved at their end(boat hub). Its been more than 1 month..and when I call on customer care evertime they say that ur product is out of stock and we are giving u alternate options you can choose from them..and we will send the product..and then after selecting product or emailing them..there is no reply or any email from boat team..they are just keep on delaying..I have called more than 10 times..and evertime every customer care say different things..like one will say ur alternate options are boat rockerz 335 and 255..and when I choose 335 they will say okay they will dispatch...but after cutting call no confirmatory email..nothing.. and when I call again after some day they will say 335 is also not available...Boat team can't keep theeir said words..I am very disappointed..I am suggesting not to order from boat again
