Lack of feedback to previous complaint

Complaint logged on the 3rd January 2016 relating to poor service was responded to by Vodacom on the 4th January stating that they would investigate the issue and get back to me. Well 16 days later and I am still waiting for a response...I do not believe any investigation has been completed, in fact I am quite sure the promised investigation has not even started.<br> <br> If you review posts on Vodacom, I do not see one smiley face, they are all sad faces showing that this is an organisation that has no time for customers and in fact this is an organisation that should be collapsed
