Vodacom: Pathetic Upgrade Systems and Procedures

I have been a Vodacom customer all my life and never had a problem to upgrade my contract. I had a 24 month contract with Vodacom that expired on 31 May 2022. I was paying R1,150 per month and never missed a payment and i have never paid my account late. I have now tried to upgrade my contract online for an amount of R1,188 per month which is R38 more than what i was paying before. Vodacom declined my upgrade and i cannot understand why, it doesn't make sense. I phoned Vodacom upgrades department and they said they will request to increase my credit. It seems they lifted it now to R880 per month. I still cannot upgrade to the device that i want due to this low amount. Vodacom does not want my business so i will have to cancel and go elsewhere. I have a perfect credit score but it doesn't matter to Vodacom. Pathetic service to a life-long customer. Margi
