DISGUSTING CUSTOMER SERVICE

I have been trying to contact MTN for the past two days now. I have sat on the call for over 30 minutes at a time. I have sent through various emails, Whatsapps, Facebook messages, through Instagram and "contact us" form on their website. I yet to receive a response. I am so frustrated and angry because I need this issue resolved in order to perform my work. MTN has been useless!! The lockdown is no excuse for bad service!!!
