Poor hadling of the problem

I bought a phone from American Swiss and returned it 4 days later.Since then I have'nt received any feedback whatsoever I am the one who has to call about the phone. I am paying for something that I am not using and it would've been great if I had been contacted about this matter and gotten either a new phone or it was repaired.its been 3 weeks now and honestly its ridiculous that I have to call and I get told that they simply \cannot get hold of Vodacom about the phone". I would like a new phone or just refund me the money.Today I got a call from the manager of American Swiss Randfontein and she tells me Vodacom took so long because of the public holidays.The long weekend passed last week and people are at work which means queries from the previous week can be handled. The manger tells me that I have no choice in the matter that it will depend on Vodacom whether or not they replace the phone. I find this to be u wrong and unfair as a customer to be treated like this.Vodacom and American Swiss are at fault because it must be the phone was faulty as they gave me phone from the display which I thought was ok because it was in the box"
