Poor service from Vodacom

Vodacom has had terrible connectivity in Mthatha for a while now. When i tried to raise the issue with them i was told to first find three more people using Vodacom that are experiencing the same problem. Why is it my duty to find three more complainants? Do i work for Vodacom? Oh and then i was told if you using study data then it's normal to have poor network? How then are we expected to study?
