Misleading Customers and *****s

Telkom Mobile is *****ing from clients, how do you offer a person 1GB for R60.00 data only and charge her subscription of R500 and say that she received a device that does not even exist on your system but keep on charging her? Are thinking customers are stupid? Contact center is very bad instead of taking accountability and resolve a query, they will move you from pillar to post. I will rather be with service provider, that we know are expensive unlike who ***** and mislead clients.
