bad customer service

Hello i went into the mtn store in the grove mall at 18:25 as the insurance had sent me an email saying to go fetch a phone, i was then assisted by the store manager there where as i showed him the email he told me i have to go print out the email, he said again i can send my wife to come claim the phone or go to kolonade branch as he was in hurry to close the store. This is not the first time i get attitude from this guy, he then told me they dont even have stock, is it my responsibility to make copies for the store?or to order stock for them? As i returned from making copies the store was already closed and it was 18:45 to start of with i was in time and instead of him helping me he gave me attitude.
