waiting for replacement

I have been told that the cellphone device i handed in is uneconomic to repair. I was then advised that i will be given a new one. This phone has been discontinued and therefore a replacement of the cellphone model i had will not be possible. I was advised that i could be given another type of model in the same ranks as the old one however, a different brand. I am not happy with that brand and would like to be compensated for the sum insured as i was told i cannot get the model i want. I am really inconvenienced as this claim has taken forever (since December 2015) because at first finrite's call centre was not answering their phones. Now they are taking forever delivering the cellphone device or even reimbursing me with the sum insured.
