Non existent sales team

I am due an upgrade May 2020 and I am now wondering why I should remain at Vodacom. I enquiries on your Facebook page if I could upgrade 2 days earlier. I was advised yes and directed to the Vodacom site which did not work. I was then asked to forward information on 3 questions needed to access my profile which I then did. Now another set of questions is asked despite not being advised of the additional questions. I asked for someone senior at 10:30 this morning. I and still waiting. Just received another message they want additional information to assist. Why send me a list of questions to access my profile the. Request more after providing them. Your sales staff are *********** and need a senior person to call me to either save my business or I go elsewhere.
