TERRIBLE SERVICE

On the 14th of April 2015 a service request (S3-82618-857WC) was logged for me as i am experiencing data usage problems on my device.Customer care mentioned i would have feed back within 24working hours....to this day i have been patient enough.I am unable to have airtime on my phone as it disappears with no explanation.As an individual that needs to constantly have airtime for business purposes,this has been a huge inconvenience.I am not happy with the way customers are handled by this network.All i want is my airtime back and and an explanation as to whats happening.
