SHOCKING lack of judgement by takealot - 7-day return policy "no matter what" is faulty

I bought myself a massager for my birthday. It arrived on 22 July and my husband quickly whisked it away into a cupboard, saying I had to wait until my birthday to open it. On 6 August (15 days later) I opened the box (which was slightly damaged, but I didn't think much of it) to discover the massager but no power connecting cable. I logged a return on takealot, asking for a replacement. They collected it and emailed a day or two later to say they have a 7-day return policy and this was outside of that time frame. I asked them to reconsider as it was a birthday present, after all. They wouldn't budge on their policy and then they SENT the massager BACK to me with NO cable. What am I supposed to do with it - it can't plug in? If they sent an incomplete item, 7 days policy or not, surely I have a right to expect a complete item that I can actually use? What does the Consumer Protection Act have to say on this?
