Do they have the correct address for you?
I suppose there is no other record of payment?
That is a problem then.
If you didn't get the documents then you can always make a stat dec to try to get this aside.
But even if you succeeded at that you would still have to show that you did make payment.
If you cant' show a payment receipt then that could be a problem.
Not really. There is no doubt that it is you. There is case law on what makes these things defective and it literally has to be such that you cannot understand it is for you.
