The same person \(2\) ... had sold it to me was there in the shop, so I explained the problem to him. The software, \(3\) ... I’d had to pay extra for, didn’t work on this machine and had crashed it.

I had to explain the problem all over again to her and she tried to say the same as the assistant and couldn’t understand \(5\) ... I was getting angry. In the end, I demanded a refund, which she eventually agreed to give me.
