Worst online purchase experience EVER

Wow, I should have looked here first but do I really have to do that before every purchase? I bought items online - all of them did not fit as they were either too big or too small. Anyway, I logged a return and the response was swift but they sent the courier to my office, which was the original delivery address. BUT I had already gone on leave for December. After the holidays, it was a long saga of trying to change the collection address to my home rather because security could assist with collection if I wasn't here. These email exchanges included correspondence from Superdry apologising for their pathetic service. Eventually, my return was collected and the refund approved (on 14 Feb). BUT then, it was a case of waiting for the refund to materialise, which it still hasn't. So I contacted Float directly (this is also annoying - that you can't just pay with your credit card but are forced to use Float when purchasing online from Superdry). AND guess what? Float said they have not received the instruction to pay the refund. Now, I'm waiting for the Superdry contact centre once again to get their act together and sort this out. These purchases were made in December and my return is still not concluded by 15 March. ***
