Begging for an Upgrade ?

On the Business Red VIP package due for an upgrade so went to Vodacom Northgate for a Samsung Edge S6. Was told I was required to pay in R159 extra per month which would make it in excess of R2200.00 per month. Pointed out the limited offer in the book exclusive for businesses , Red Executive for R2099 per month. Salesman said I would need a quote done ? Why a quote when the deal is in the Vodacom store booklet ? Told me to come back on the 1 May 15 so I informed him the deal ended 30 April 15 , his reply was I need to come back the1 May. Phoned *** said they could not help as they don't do red packages I must phone *** who said they don't do upgrades I should phone *** who said they deal with accounts so I should phone *** who informed me to phone the first number ***. I have experienced numerous problems with Vodacom service and hence I have an account with Telkom as well. Vodacoms arrogance is certainly assisting Telkoms growth. Still no answers.
