Hi T-mobile,
As I canceled my subscription with the TV box, I sent it back, and confirmed that it has been delivered from PostNL Long time ago.
But I got a paper mail saying that it hasn’t been returned and I will be charged.
Can you please check this case?
The tracking number is 3SLFVZ701760555.
I only have online return receipt because I didn’t ask for a paper receipt.
Regards,
Y
