Multichoice

Multichoice locked my router cause I took it to work. I tried sending them emails but they only respond by sending me reference numbers and directing me to speak with an agent of which I can't get hold of since yesterday morning. Im paying them every month. But now I find myself in a situation whereby I must always beg them to unlock it. They were very nice when they introduced this offer to me . Now they are showing me their true colours . It's either they unlock it or come fetch their router it's not only Multichoice that offer wifi services. Their service is really disgusting
