extremly bad service

On 10 March 2016 Round about 12:30 i phoned vodacom to do a upgrade on my cellphone account to a Samsung S7 edge the lady i spoke to done the upgrade to a Silver S7 Edge and told me at the end that i will receive my cellphone in two or three working days. On the 14 March i phoned vodacom to find out more or less when and what time will i reveive this cellphone. The first lady i spoke to just hanged up the phone the second time i phoned a guy spoke to me and said sorry i will not get my phone today or tomorrow but maybe next week when i started saying but the lady i spoke to when upgading told me that it will take only two or three working days he strated getting a attituade towards me because i was promised something and now they cant Delliver that phone to me and the more i wanted to talk the more he started to interuping me while speaking and not giving the customer a chanse to speak how Rude from vodacom Customer desk so i told the guy i want my phone at the latest tomorrow i dont care how but if not im going yo take it higer to the news papers. You cant advertise and not provide and still tell you you will have that phone in two or three working days.
