Unimpressed

We placed an order for a 3m sliding door, received it, didn't check it seeing we trusted that we'd receive the correct item, yesterday, when we wanted to install the sliding door we were quite surprised to see that the actual door is the correct size, but the frame is too small, we received a 2.7m frame, we phoned customer service, spoke to a person who wasn't very helpful, we have no idea when the courier is coming to pick up the door and when we'll be receiving the correct door and until whenever that happens we have to sleep in a room that's basically open...so I could get out of bed one night to go to the bathroom and someone could've just walked right in...
