bad customer service

I upgraded telephonically on the 2 Feb 2015 & was told that delivery of the phone will be made on Wed the 4th Feb.When i did the follow up on Wed ,i was told a different story that the delivery will be the following day.On Thursday the following day i still couldn't receive the phone and bearing in mind that i had to take a half day at work just to be at home for the delivery.I spoke to the supervisor Bhekumuzi at Vodacom upgrades call centre and explain the costs I'm incuring in waiting for the phone .I even contacted the courier with my own money n to be told they got instructions from Vodacom to hold back deliveries for risk assessment .According to Vodacom my delivery was not suppose to wait for assessment as security check was done with me.I was then promised Friday the 6th which i thn told them i will be at wrk so thy must deliver at wrk.i gave them my work address and requested it be delivered b4 10am which they agreed and it never happen.the courier said they were never given the work address so they can't bring it there 2day only on Mon the 9th.i ended up cancelling the order.So disappointing that Vodacom after many yrs with them they give me such a worse servc
