MTN Customer care line rude agents

Customer care line is full of rude agents and their managers don't want to assist irate customers. My phone I was unable to make calls it kept on saying I don't have sufficient funds to make a call of which I did so I called 135 they kept on telling me different stories till I found some stupid rude agents such as Elsie mgiba, olwethu shange to mention a few I have recordings of what they were saying to me and I have their names and surname I tried reporting this to their floor manager Mervin Pillay and lungile skhakhane manager in JHB I have their email addresses they didn't get back to me in regarding this issue they kept on telling their agents to say they are on a call they must take my details. MTN has poor customer service all they know is to debit us every month but when you have issues agents fail to assist they become rude then hung up on us
