Call centre operators lie, in-store staff don't do their jobs

I bought a wifi router yesterday and have had endless problems! The supervisor at i'langa mall in Nelspruit sold me the sim and router without bothering to activate it. I spent 2 hours on the phone after I got home to try to get it to work. I then had the pleasure of dealing with Lulama (not sure if its her real name). She sounded like she was sleeping into the phone. She didn't listen to a word I said, couldn't help me and when I asked her for a reference for the call she made one up! This morning Vodacom told me they don't give those kinds of reference numbers!! I am shocked at the level of dishonesty from a Vodacom call centre operator. I then had to phone back and got through to Neo, who was supposed to call me back. I'm still waiting for that phone call - 12 hours later!
