Zero customer support from MTN when they blacklisted my phone out of the blue

MTN blacklisted my Note10+ out of the blue after a year of use. I had purchased from Takealot in September 2021 and assumed all is well. A whole year later I lose connectivity and I cannot contact MTN to state my case and ask for apply for unblacklisting. In fact I got most of my information from Vodacom's unblacklist agency as MTN either has no information or sends you to voicebots who cannot help. Absolutely disgusting that MTN will essentially brick a device and put a customer at risk without checking facts
