Bad service

Ive been a loyal customer for a lkng time and then after placing an order I got a message of delivery after waiting for 2hours the delivery got cancelled. I didn't receive the order. I must say this is the worst service the online service ever received . Try to contact them no luck. Even sent a whatsapp still waiting after 4hours for a reply.. Now I have to wait 10 days for money... this is really not fair.
