Horrible customer service from Vodacom!!!!!

Vodacom has the worst customer service of all the companies I have dealt with. I have had a contract with them since 2009 and have had endless problems especially when having to do upgrades. Not sure why i'm still with them! Its like being in an abusive relationship. The recent incident happened when I phoned in regarding a cancellation on one of my contracts, the lady I spoke to advised me that I could upgrade my other contracts and proceeded to give me the phones that I could upgrade to as well as the packages. We settled on the phones and the packages and I received it in record time but the excitement was short lived. Firstly the one phone was the incorrect color and the other phone was not the phone we agreed on. My husband decided to keep the phone that was the incorrect color and I had to do the phoning around to get the actual phone we discussed. A few days later my husband noticed that when he checks his balance it reflects that his "bill so far is 300 and odd rands" , I then phoned Vodacom again and was advised that the amount reflecting was only the amount for all my contracts combined and there was nothing to worry about, but lo and behold I get a bill reflecting and amount owed to Vodacom of R1436.05. When I phone in again, I am transferred from pillar to post and a rude "lady" named PALESA from the upgrade department keeps dropping the phone in my ear. I then get through to someone that says I cannot have the contract that I signed up for because its no longer valid (it was an online application) but I phoned the VODACOM CANCELLATION DEPARTMENT. I have never been this ****ed off in my entire life and am seriously cancelling my contracts one by one!!!!!!
