Vodacom the worst service provider in the industry

I have been trying to upgrade my phone since January, needless to say I have to date not been able to do so with numerous phone calls and empty promises from upgrades and customer care consultants that they will rectify the matter and contact me which however never happens, RAM is a issue on it's own but as Vodacom is using RAM for the deliveries it is without fail the worst courier company. Just a bit of background, phone upgraded in January, returned twice as phone were faulty, Vodacom eventually cancelled upgrade in March in order to start a fresh, I was then able to upgrade in April which I did, I have still not received my phone as RAM stated unsuccessful delivery, after various calls to Vodacom and RAM which could never trace my parcel even with reference number from Vodacom, my phone was returned to Vodacom again. Now I was advised that the phone I upgraded to is no longer in stock. I have never in my life had such bad service, you can actually not complain about the service as there is no service.
