Vodacom going from bad to worse

I am yet to get to a pint where I can say it was a pleasure to deal with Vodacom. Not a single encounter with Vodacom has been a pleasant one. I upgraded one of my lines earlier this week. I informed both the agent who assisted me and the person who called the next day to verify that I shall be out of Town this week and not be at office to take receipt of the handset. I was informed that I should hand a copy of my ID, proof of address and a letter authorising my PA to take receipt on my behalf. This is actually how it was done twice before. On Wednesday when the device was ready for delivery, I was informed by RAM couriers that Vodacom instructed them not to hand to a third party. Why on earth tell me one story and then procedure is different. This is so frustrating and I think the Vodacom staff are so unprofessional and ill informed. This is the worse service delivery ever and it just never seems to improve.
