Boat — They are not receiving my calls

I have called so many times to boat customer service but they didn't take any call. They had took my boat rockerz 255 red but didn't give me replacement product. My ticket number is 1267640. They said they will replace my product within 7 days and the next day it is saying that it takes upto 12-15 days. Now the 15 days are over and my product is still not received.
And now they are also not receiving the call.

Dear boat you are one of my favourite product but your service disappointed me very much.

Please solve my issue as much soon as possible.
