Branch Manager's extreme rudeness towards customer

I got SKU codes on MRP Clothing web site and phoned MR Price Atterbury to find out if they have it in stock. They didn't answer so I tried to get through to them via their Customer care and succeeded after 30 minutes after someone at the branch let me hold on for some time and I have to phone in again. I complaint to the lady that answered about this problem and asked her if could check on the SKU codes if they have it in stock but all reaction I got from her is that she asked me what my name is. I told her and then she go on in an extremely rude tone telling me \O so now you want these clothes so that you can bring it back again". I asked her what her name is and she said it is Bonzo. I asked her why she is so rude to me and I will report her if she has this attitude. She said that she doesn't care I can do that. I asked if she is the Store Manager so she said she is. I asked her again why she is so rude and she said she doesn't care if I feel she is rude. I said I don't feel that way"
