Cell C and their poor Sevice!!

The issue that I have experienced was: I loaded a 3gig data bundle and the next day it depleted. I then loaded a 5 gig on the 15th of September and the next day it depleted again!!! Cell C is *****ing me!! They have poor customer service!! When I tried to resolve it with their Technical team, the consultant hung up and disrespected me!! I called to speak the manager by the name of Jabulani and he and his consultants laughed while we tried to resolve this!! Check your employees and their poor service. This is pathetic.
