What was on the email and agreed on, wasn't there

I received my goods on Saturday but when I opened it there was something missing which was on the advert they sent me and agreed on it. What was on advert was a laptop, tablet and free gifts which are memory card, flip case for tablet and headphone. the problem is the headphones were not there. I sent an email to Stephan Hill who sent me the email (Adv.) who didn't bother to respond, that was on 14-09-2015 at 09:40. The following day I called and I ended up speaking to Chisman (Manager) who told me that advert was expired and when I told him that the contract was for ordering what I saw on the advert. He promised to call me back, that was 15-09-2015. After that when I call and ask for him I 'm being told that he is busy they will let him know and call me back. Today's date is 23-09-2015 and I haven't heard from him or any one from Fonechoise. I am really disappointed and not happy about how they operate. This is a very bad way to trap your customers, promise them this and that and change your words on delivery and to make me a stupid. I have made several calls with my money, and it has been 9 day since waiting for the response from Chisman. Very bad, poor, untrue service.
