Vodacom online Upgrade ****piest service ever

This is the 2nd review I'm writing for the same issue. Settle in, its a long one... Over a month ago (24 February) I requested an online upgrade. I received an email confirmation which said I would be called in 24 hours but that never happened, about 4 days later I received an email from RAM couriers saying they had tried to deliver on the 27th but no one was home (someone was) and they tried to call 3 times but were unsuccessful (zero missed calls received). I rep**** to this email and someone called to say they would deliver the following day, Friday 2 March. No one arrived that day and no one called. About a week later I contacted Vodacom only to be told they had sent the package back to the warehouse and I should reapply. I was understandably upset but reapp**** anyway. Someone called me, only to tell me that they could not process the order until the previous one (that Vodacom stuffed up) was cancelled. By the account holder, who lives overseas. Eventually, after having the phone put down on me and much thought I decided to email the social media address again. They managed to assist me with cancelling the order by contacting the account holder. I duly reapp**** and, since then, have heard nothing. I've emailed the social media address, as well as ********** an address given to me by the social media department but no one gets back to me, no one calls. What must I do, Vodacom? What must I do to give YOU more money? Or shall I just go elsewhere?
