Shockingly bad vodacom response and service!!!!!!

I upgrade my contract, i have now emailed, made contact through fb and even called into the vodacom call Centre (my call gets cut) and nobody wants to reply. I upgraded and my upgrade was canceled the same day. I went into the shop and noboby can give me answers, it's been 3 days since my fb post and vodacom has not responded!!!!!!! Shocking and sad have been a happy vodacom customer for the past 10 years :(.
