Bad service Vodacom Cresta

I went to Vodacom Cresta to upgrade a RED VIP contract. I was given a 16GB contract (I'm a PA), my boss wants 64GB and also stated that the phone has a speaker problem. I was assisted by A consultant by the name of Lucky, when I took back the phone today he said said he can't assist he then referred me to his supervisor who also said he can't assit. I then went to Sandton branch I was assisted by a lady by the name of Amanda and she phoned the Cresta branch she spoke with the manager (Ricardo Vanboomen) who was very rude and made it clear that he will not assist. <br> <br> Please help as we want another phone and not this one.
