Failure to respond and resolve matter even after 1 whole month

Even after escalating the matter to the CEO’s office, I have received no assistance. It has now been over a month, and Vodacom has still not resolved my issue. Every time I try to call the CEO’s office, the phone just rings until the line drops. This has been happening since Thursday afternoon, when the CEO’s representative was supposed to get back to me. Vodacom are misleading the public at large
