Last night i was ****** and my MTN Contract phone was ******, i couldn't call MTN to have the prone blocked due to loadshedding and bad network, this morning when i called i was asked for my details only to be told the system is not working, it apparently has issues, i mean my phone is ****** and i cant lock it because my provider has system issues, so now the people who have my phone can assess my information such as my banking apps, service is 100% bad
