Very slow refund process with no feedback

Beware of ordering online. After 7 days of not receiving any status updates or feedback on my order I found the products elsewhere and cancelled the this order. I confirmed my back details on 14 Dec and on 22 Dec I still have not received the refund. I requested updates via their support email with my reference number and they just don't respond. I called the call centre yesterday and the agent promised to call back within 10 mins with an update - needless to say I am still waiting for that call. I called in again today and the refund was apparently done but it will take 7-10 working days to reflect - which is ridiculous by anyone's standards. Anyway - I shall wait and see!
