Pathetic online returns

I have just returned a shoe to be exchanged for a smaller size, which I indicated about 3 times in emails.

CUM has no system to update customers on what is happening with returns. You have to chase them.

Then they tell me the refund has been processed.

I did not even request a refund. Tried calling and emailing them and received no response or the same response on the refund.

I would never buy stuff from them again as they have no idea how to treat customers.
