BAD SERVICES - PROMISES

I have been phoning Vodacom since Tuesday evening as I am in my 19th month of my contract, but in November 2014 my Blackberry 9720 charging port was faulty and I had to take my phone to Vodacom which is the closest one is Cresta Vodacom after 2 days I get a call-they have to replace the phone as it cannot be repaired, JA right a new phone - it wasn't in a box per a NEW phone but in a plastic packet. FINE - now again the phone has the exact same problem. I expect better service this time around from Vodacom as this is the 2nd time in my 24 month contract. I leave home at 6:08 in the morning and only get home at 6:30 or 7 o'clock at night. I work in Braamfontein and don't drive so for definite I will NOT walk around as a lady try to find a vodashop to assist me. Then I get promises this morning that I will be call they will make an appointment with me to come to me and see if the phone can be repaired and if not they will replace the phone immediately. At 15:20 I started to call Vodacom again and guess what the person I spoke to this morning is just GONE!!!! Now I again spoke to someone and told ooo nooooo 24 hour turn around. This is really freaking sick GUYs!!!
