Third time lucky.. or not?

I ordered 9 large tins of dog food on the 9th of October, what was delivered was 6 large and 3 small tins. I phoned the helpdesk and they arranged a collection and a delivery which for some reason could not be at the same time. The 3 small tins were collected and a few days later again 3 small tins were delivered instead of the 3 large tins. Again I contacted the helpdesk and again they arranged a collection and a delivery which were to be on separate days. On delivery is would seem 2 large tins and 1 small tin was delivered instead of the 3 large tins. I have logged another dispute and have now been ignored for the past three days. <br> It is utterly unacceptable that it takes weeks to sort out a basic mistake and 5 visits by delivery companies for which I have to make myself available. If you are unable to deliver the product don't sell it, from a long standing client (Take2) this has been thoroughly disappointing. Oh and I am still waiting for the correct order or for someone to contact me regarding this.
