Long lead time, undelivered items, no refund

Order placed on 10 February and received on 7 April. This is over 40 working days, not the 14-18 advertised. I was not kept informed and had to constantly request updates. In addition to the delay, only half the items were received. I requested a refund for the undelievered items. I was told this is not their policy and I can order something else. I do not want anything else that they offer (especially not with such poor service), I want a refund so that I can buy the desired item elsewhere. As per the Consumer Protection Act it is my right to choose a refund and they refuse to honour this. They are spending their time fighting with me about this rather than just simply issuing the refund. From this experience and the other reviews here, I can only conclude that there is something very dodgy about this company and I would recommend that other buyers beware.
