Terrible customer service at MTN!!!

<p>Hi..i am with my as my service provider. I currently have a 10gb Wi-Fi router. Every time I get recharged with data in is depleted within 3-4 days. This even happens when I was away in December. I have called and called with no feedback. The service is absolutely terrible and useless. I am paying for a service I do not get!!! And then I have to deal with bad service. </p>
