Attention stolen goods! Better stay away ...

Good day!
We have moved into the receiver a little over a week and now discovered by activation problems and a telephone conversation with sky, that the devices are stolen goods! After the double adjustment of the serial number with sky, they confirmed the specified receiver is already registered as a rental receiver to a customer and these provide an indication wird.Mal'll see how it goes!
If that does not matter, can securely access. However, I find this kind of doing business very questionable ...
