Hi and Welcome to the Community!
Please see this helpful thread to start:
If you have used up all of your chances to enter the correct unlock code, there is nothing further you can do. Even if you happen to have now the correct code, it is useless. Only the factory can now (legally) unlock your BB. Typically, I've heard that the cost of having RIM do this for you will be greater than the cost of just buying a new one. But, you are able to ask them...see here:
Note, however, that this process will start with a fee...
If you obtained your unlock code from somewhere but it was incorrect, your recourse could be with them -- however, they may well question why you exhausted all 10 attempts before contacting them.
If your BB was already MEP locked and you obtained it from a source that represented it as being able to be unlocked, then your recourse would be with the seller you obtained it from.
