Extremely disappointed

I am so disappointed with a call that I just received from Bradlows. Lebohang from headoffice called me to offer a store card and also called my work place. I asked him why did you call my office why couldn’t you wait for me to answer the phone and he told me they can call anywhere if they are looking for me. That is not right and I totally disagree. My colleagues are telling me that Bradlows is trying to call me and that is so embarrassing. His response was also very disrespectful. Extremely disappointing and I am sure now that I do not want the store card because Lebohang was very very disrespectful and i do not wish to continue buying from their stores
