Vodacom unblacklisting department

Hello peter I,ve got a Sony Z5 cellphone Imei. ********** ********** 4 which was blacklisted by Vodacom . I went to vodashop get my phone to be unblacklisted few days later I was told it unblacklisted. The funny part is my phone working with all SA network now is only working Vodacom network the other network says not registering on the network.

I went back to vodashop they said there's nothing more they can do to assist me, so please I need my phone to be unblacklisted also on the other network
