Pointing Fingers

I went to Vodacom in Greenstone by Game on Saturday to port my number from a different service provider. I was told that they did not do ports on the weekend, only Mon-Thurs. While walking to the bank area I came across another Vodacom so I went in and asked the same thing, and they told me that the other store had been lying. I left and went back to the first store on Sunday, and they told me that the second store was lying. Is this kind of customer service a norm for Vodacom?
