No Care at Multi-Choice

Came in to the Customer Care Centre to get a Switch which a consultant on the phone had advised I do a few days ago. I had also upgraded my package on the phone and was told it was all sorted out. The woman who helped me was rude and aggressive. Said nothing had been done, I had no contract and the information I had received was incorrect. When I tried to explain what I had been told on the phone she just spoke over me and wasnt interested. When I told her she was rude she just called the person behind me to help her. How do you employ someone like this in a so-called Customer Care Centre? Absolutely appalling service!
