Bad Customer Service

Hi

I ordered a dress from Zando on 28/11/2018 and paid with my credit card and on the same day i received e-mails regarding my order the first was *ORDER RECEIVED AWAITING PAYMENT ,2nd *PAYMENT RECEIVED and 3rd *ORDER CANCELLED. Iam worried now because I payed and I have been trying to call since that day and enquire about my order but I cant get hold of Zando. When I track the my order online its says order awaiting payment but I payed. Was supposed to receive my parcel yesterday but still waiting. Kindly assist...
