Seasonal tickets

Saturday we went to the Springbok game on Emirates Park. We had seasonal tickets which means that we can go watch any game at Emirates Park including international games. We got to our seats to find that they made a double booking. We called the manager and he said he'll sort it out.. he didn't even come back to us and **** to us about it. We had to sit on different seats because of this problem! I don't know who is responsible for this mistake, Emirates Park or Computicket, but it is unacceptable!!!
