Seven months and still no resolution!

Like many other people have posted, my trade in seems to have disappeared between the USPS station and Assurant. 

When I began this odyssey, I was initially told they received the phone and it was broken. After about a month of that, suddenly they had never even received it. 

I have literally spent days on the phone over the last several months trying to get this resolved. 

Usually the multi hour calls end with a credit to the account for the amount I should be receiving anyway, while they do more "research" .

I have been a customer for almost a decade and cannot believe how badly they are handling this. What legitimate company thinks it's okay to drag a customer through something like this?

I am beyond frustrated and do not understand why their service has become so terrible.
