No service at all

On Black Friday the 24.11.17 I ordered and paid online for 2 pairs of boots from Crocs SA. Up until today I only received 1 pair that's to small! I've been leaving messages for the call center because apparently they are very busy and couldn't take my calls, sending mails and messages on FB messenger. Well it seems like they are not interested in helping customers resolving their problems! Order number 20932 - I received the Crocs Freesail Rain Boot on waybill number S ********** , it's to small so I tried to the what must I do to exchange it for a bigger number! No luck yet! The a-leigh Leather Boots I did not receive and it seems I am going to get it! I am really sick and tried of trying to contact them! R1070.00 later and I only have 1 pair of to small boots to show for it!!!!!!! This is the worst service ever!!!!!
