I had my mobilnr.  First over my sisters contract with tre. Now i took it over in an own contract, but in “mitt tre" is no abbonement registered and no avtal. Also i cannot open and read the överlåtelse contract,  which is laid there. Every programm says the fileending is wrong.

Contacting the service they ask for the last avtal and the abbonemang, which i don’t have in mitt tre. Only standardmails, no help from the service.

What should i do to get information about if the överlåtelse worked? The nr. still works, that is the only good thing.
