Never ever upgrade with Vodacom!!!!!

I have been struggling since 29 May to get my contract renewed. I've never in my life had to make so many follow up calls because Vodacom employees and management just don't get back to you even if they promised that they will phone you at a certain time. I dare the Vodacom representative that will hopefully address my complaint to review the calls I have made to their customer care number, to Jenny the manager on ********** as well as Phillip also a manager on ********** . My ordeal started with Melvin, transferred to Aiden, then Jenny stepped in that also ignored each and every of my calls after asking me to contact her on her cell, then I escalated to Edward that was also a no show with only promises and eventually ignoring me and then Finally Phillip that is now also avoiding me completely. I can't understand how difficult it can be to do an upgrade and to get the actual handset. I am utterly disgusted about the promises Phillip made purely to keep me happy and after I phoned the couriers directly, found out that they were blatant lies. Now I don't even have an idea when I will receive my phone after I offered to pick it up myself and explaining that I actually have a day job that entails visiting clients and being on the road. I had to make special arrangements on Phillip's instruction to work from home Monday and Tuesday just to have a no show courier because he forgot about me. I would seriously advise any person that even mention Vodacom to run far, far away because they clearly don't care about their customers if Managers act in such a manner. I would have had more success if I took a donkey and travelled to Vodaworld to take out a new contract than had to deal with their upgrades department. I was patient, I shouted at them and even literally cried and begged - all to no avail. And the cherry on top is that I mentioned last week already that I am dealing with a serious family crisis where my little girl needs to go for tests so I really just need this to be sorted since I can't be distracted by a cellphone upgrade and none of them has shown any interest in sorting this out for me. Please, please, please assist since I feel I have now exhausted all avenues.
