I bought a Mifi device from your shop at Ikeja City mall
S/N 320513884549
IMEI: 867462052329632
and MTN line 08104170681
and I was told I will get twice the data I purchase...
I am sorry about your missing line.
You will not be able to do a sim swap on a line that was not registered by you. However, ask MyCustomer who registered the line to visit...
