MTN dialling voicebox (100) goes to 112..

[redarrow]

Lately I'm having this strange issue on MTN (prepaid) where trying to dial my voicebox (100) gets me through to the emergency number (112), I dunno how the heck this happens, it's random, at times it works ok.
Right now it's doing it again, can't get to my dam voicebox.

Anyone else ever experience this?
