poor service

Good day DLH is ******** customers I bought an item with dressinn order number ***3 last week Friday on the 23 April 2021 the item was about R865.49 and the shipment was R1,386.44 and the total amount went to R2,251.93I agreed I paid the amount. I was not told about the extra amount . they didn't come back to me till i made follow-up. the boring part is they were telling me to pay extra payment. so they edited email while i was talking to them on the phone. the y ladies whom i spoke they didn't even telling the way forward neither solution instead they wanted to blame me. I have spent my airtime(hour) to call them . So i need my money back. here is my numbers *** /***.
