BAD SERVICE VODACOM

Today I was humilited by the manager Ulrich Prins of Vodacom Cape Gate. I had a querre regarding a sim swop and was busy talking but he keep interrupting me and do not listen to what I have to say. Keep telling me I am rude to him but in the mean time he is the one not listening to me and after I told him to please listen he shouted at me over the phone and put the phone down in my ear. I am the customer. I and also work with clients the whole day. I was told that now matter how wrong a customer is you still treat him/her with respect and listen to what your customer has to say before you climb on your high horse and be rude to a person that is simply trying to explain what she wanted as I was on the phone to vodacom the hole morning being put through from the one department to the other and Vodacom does not communicate back with his client after we have been to the shop on the 3rd of April and still the problem is not resolved. I think he is not fit to be a manager of a shop. If he speaks to customer like that how does he treat his staff. Please sort this out.
