TERRIBLE SERVICE FOR A NEW CUSTOMER

Last week I was assisted by an agent with a new contract. I clearly told both the sales agent and agent that called to confirm my order about the address. If they delivered last week Friday they would use my home address and if they delivered today they would use y work address. I called Ram today was told that they are delivering to my home address! I am not at home today!!!! I contacted Vodacom for assistance and the agent tell me, she will change the address and the delivery will take another 3 - 5 working days! I asked for a managers email address, she gives me me the email address for the admin department and disconnects our chat!. Why should I wait another 3-5 workings days for something that was not my mistake!. If i am receiving such terrible service as a new customer, when I did not even receive my device as yet! what will happened over the next 24 months????
