Immediate bad customer service - new contracts

I'm a new customer; I took out 2 cellphone contracts 3 weeks ago. Since then:

1. My old cell number has not ported. I was told this would take 3 days. 2. The phone I ordered with the second contract still hasn't arrived.

The first person I spoke to in store told me he was very sorry, but it was probably MTN's fault about my cell number, and in terms of the phone, he had absolutely no idea where the phone was and it was impossible to track. The second person I spoke to disappeared into the back and then told me they hadn't even received a response from the warehouse yet. This leaves me feeling that the first person was simply trying to get me to leave the store. I don't appreciate being **** to.

Cell C informs me that they have stock of the phone. If they have it, why are you having such trouble?

I've been a customer of yours for 3 weeks. These immediate problems make me very nervous, and I want to cancel both contracts and move to a more reliable network, to be honest. Please rectify, else I am going to do so.
