Vodacom's customer service is appaling!!!

I took a contract for 2 Iphones from Vodacom at the Pavillion in Westville Durban this Sunday. I got home and found out that the batteries on both phones are faulty after I had enquired about them before taking the contract and was advised they are on good shape. I was charged a pro-rata for the phones but now I don't have them with since I had to take them back and they had to go God knows where for fixing yet I still haven’t received any feedback regarding my refund cos I cant be paying a prorate for phones that are not in my possession, not to mention a contract that I took under the provision of incorrect information. This is not in line with TCF and I will be taking this up with the ombudsman if need be. Such service is appalling for such a big company.
