Bad attitude

i walked in to the store for repair and ladies address me in afrikaans even if i spoke english after told me to call back tomorrow and find out if there is stock available (is that a service what dont they call me back?) the next day i cal to find out whether there is stock available there is no stock when iam asking when their courier is going to deliver she dont know and must keep on calling and hang up the phone on me. she hang uop on i am paying for the time that decoder is not working and why is she not taking that decoder and call me back or find out when the courier is going to deliver and call me back where is the customer service we are paying for?
