Refuse to cancel order

Wouldn't recommend them,they don't reply emails nor whatsapp if they do thn it will be 3 or 4 days thn they reply,I was a customer by them for years and so disappointed in them on 29th August I ordered wrong sizes for my clients I called them to ask if I can cancel and order again they say no cause my order was already processed and that was a very big lie cause on my app till today it states order received nothing about order being processed,now I will have alot of tracksuits that my clients don't want and I must buy now other tracksuits out of my own pocket cause my customer Don weat the sizes I ordered bunch of skelims
