network issues and no response

you have network issues without any notification and then i get told that the IT department must send out a notification to customers, i do not care who is responsible to send out the notice. this is a **** network never inform anyone of anything and useless people working in the call centre. I tried to make an emergency call yesterday, as my aunt passed away and I couldnt due to me having insufficient airtime and I have R24.00 airtime. you dont care if its an emergency you will leave customers to be in serious incidents and then they cant phone out then i call mtn and they say there is a network issue. why was any customer not notified? also my data has been used up extremely quickly compared to previous months when my cousin messaged me on whats app the afternoon to tell me of my aunts passing i only got the message when i got home yesterday evening due to network issues. I want to be reimbursed for my data that has been flying and i do not know why and I want the call center OPERATIONAL MANAGER TO CALL ME, NOT A TEAM LEADER, THIS BETTER BE ESCALATED ACCORDINGLY! I WANT MY DATA AND SOLID NETWORK!!!
