NO APPOLOGY FOR BAD SERVICE

I bought a phone Galaxy A3 LTE on 17-02-2015, then decided that I want Galaxy A5 instead of A3 then I took a phone back on 20-02-2015 of which the sales person wasnt happy, she took it back and said she will call me in 2 Weeks of which it will be 1st week of March to tell me whether they have accepted my request. I waited for call till Friday 06-03-15 @ 12:00 as I called Vodacom shop to hear whats happening,I was told that Consultant was off that day and requested to speak to Manager, spoke to Manager told her my trouble and she took my details and said its only consultant who can help me with the phone and the consultant will be at work at 14:00 the Manager said will make sure consultant calls me when she arrives.I called @ 16:00 Consultant said she emailed me of which I havent received any email from her even today I have no email from her told her arrangement was to call me not email and told her that I left my work number she said she called nobody answered of which its a LIE um the Secretary. She said she doesnt have A5 phone and she can refer me to another store if um not happy with her service, NO APPOLOGY FROM HER FOR ALL THAT SHE DID SHE ONLY HAD ATTITUDE TO OFFER.!!!
