Bad experience with takealot

I purchased 4 items from takealot (sofa covers). The covers did not fit my sofas nicely so unfortunately had to return them as much as I liked them. I filled in the return forms to get a refund. When completing the form online I was only given an option to return 1 or 2 items and since nowhere mentions that one can fill in 2 forms, I picked 2 items and under additional notes made a note to say I am returning all 4 items purchased but the option will only mention 2 items as no option is given to mention 4 items. The driver came to collect the items and after a week or so I only got a refund for 2 of the items. Upon querying why I did not get a refund back for the other 2 items takealot said they would investigate this. Very delayed services so a while later i was told that I only returned 2 items as the return form only mentioned 2 items. Back and forth for 2 months and takealot insists that I only returned 2 items and are now refusing to give the refund of the other 2 items. I told them i will no longer use takealot and tell everyone of my experience and this made no difference to them at all.
