MTN month -month ****!!

MTN month to month router is a ****. When you take the router they lie to you!!. I called to cancel this nonsense of a router after they didn’t load my data. When I wanted to cancel they said I owe 280 for what? Because this is a month to month ?. Now I am trying to cancel this thing and I do not get any help they say they will blacklist me I have to pay R580 before they can take back their router!!!. So whatever you do do not take that MTN nonsense !!!
