Bad service from MTN

I took out a contract from MTN 2 weeks ago. The lady told me that the phone (I phone SE) would be deliverd last week and that i should use up all my data and airtime because it will not be carried over from vodacom to my new contract. I've since then used up all my data and airtime and have had to buy more because the phone has still not been deliverd! I wanted to come over to mtn because apparently you are the best network in SA but your service I have to say is terrible!!!!! I had to call the shop and find out whats going on nobody even thought of calling to say that it will take longer because they have no stock! Why advertise something if you dont have stoc****! Can someone from mtn please contact me and give me info because nobody seems to know when I will get my phone
