Aftershock London Tracking Order Status

So, this company were excellent with responding to queries and delivery. Responded well to sorting return. But since I returned my order - it has been 3 weeks and no refund, no response to emails now after being so prompt before. Odd right? Responded so kindly and promptly when buying and when wanting to return but go into silence when chasing a refund. It appears this company may be a scam. I would appreciate a response to my emails and a refund asap.

I ordered the Flory Navy Maxi Dress and it arrived quickly. The item is a beautiful all over sequin dress and the fit was perfect. I've ordered more things since then and the customer service throughout has been excellent.

Sent return in 3 weeks ago,no acknowledgement and no reply to 3 emails!

Placed an order and need to return as it seems their sizing is not correct on their website. I’ve emailed for a return note, as that is their way to handle returns and I have had no acknowledgment.
