I went to port my number over to vodacom from telkom and my SIM card didn’t connect to the network so i took it to the istore where they told me my phone has been blacklisted and that i should go to vodacom to get it taken off however i was continuously told that my phone was the problem when my sim card worked fine before the porting of the number. i’ve spent almost R100 on sim swaps and wasted whole days trying to get it sorted. the customer service been subpar at getting a clear answer as to why my phone doesn’t connect
