Poor service

On Friday 21 July I got a data router from MTN kokstad on a month to month basis and iam unable to get connected. Each time I call their number Noone picks up. When I call their call centre there is no option for someone who doesn't have an mtn number.. I therfore cannot get through. I live 70km away from the store and not possible for me to drive there. Iam sad because I already paid but not getting any service
