Agent refuses to have sales call me back

My contract expired last year and I did not take up a new phone as my old one was in a good condition. I opted for the data only contract. My phone is now giving me a problem so I called Vodacom to find out what were my options.<br> <br> 30 min later...I was advised I could only upgrade next year or pay a R1 800 cancellation fee. Option 3 was to open a new lline however the agent plain down refused to take down my details and get them to call me stating she has no communication with sales as she is upgrades. She didn't even want to send an email to them. Im shocked at the unwillingness to assist. Being a Vodacom customer for years I'm disguised at the lack of empathy especially because I had waited about 20 min for them to pick up.<br> When I eventually gave up on arguing with the lady I took the sales number she gave me and decided to call them only to find they are closed. Really disappointed at Vodacom #AsIMoveToCellC
