BAD SERVICE VODACOM

I upgraded my contract about 2 weeks ago. Till today I did not receive my new phone. The person who read my complaint on Vodacom contact me and told me customer care will contact me. Another person from Vodacom contact me and told me the agents made a fault on my contract and apologized about it and told me Vodacom will give me an extra 110minutes on my contract free. When I spoke to the person who called me from Vodacom he told me that he cannot find any information that a person called me. Why would I lie about it? They cancelled the delivery on the phone because Vodacom told me they cannot get hold of me. Another lie because my phone is always with me. I received calls and when I pick up the person on the other side put the phone down. Customer care told me they will ask the agent to contact me but I am still waiting. This is very bad service from them.
