Wrong info

MTN has given the wrong email address to the Nu Dept collection company . I am not the person connected to this account , but keep receiving the emails from this company. I have confirmed with MTN regarding my account and I am up to date with my payments. I have contacted MTN regarding what to do with this matter , but have not received any response . Correct this mistake as it is a real inconvenience. If this continues I will not be using MTN again
