MTN shocking service

I requested MTN to cancel my deceased Mom’s policy, provided her ID and death certificate. They cancelled my personal contract. Legal dept can’t read. I have tried for 3 days to get my own policy re-instated. All I get is “escalated to legal”, legal dept does not respond to emails. I can’t call nor can clients call me. Three days later it’s still escalated to legal via customer care, via FB etc. Pathetic and shocking. When you mess up my business and don’t act to rectify your mistake ... I’m still waiting ... I can’t migrate my number as it does not belong to me anymore. Thanks MTN ...
