Bad service

I've been a customer of Vodacom, when they started in our land. I run a business, i complaint about two numbers that is on contract, that i don't have. Nobody can help me with it, still paying.

i have about 7 phones, two of them is for upgrading. I went to Vodacom4u in Cape Gate, they gave me a guy, by whom i can upgrade, but for all the phones that I'm interested, there is no stock left, he cant tell me what phones i will receive when i upgraded. But strange, all the phones, that i wished for, is still available in the catalogue. It feels as if i must stop my business at Vodacom, because the upgrade is really a downgrade.
