MTN

Hey my name is Samukelisiwe Ngcobo I have an contract with MTN it's been 4 years with them everything was good until this year April my bill went up but R1000 I called them asking what is the problem they told me that the consultant that was helping me with an upgrade did an open line without my consent and I told them to close that open line but they didn't, now they suspended my account telling me that I owe R6000.
