Terrible service

I bought three items from takeloton the 20 September 2022 and the items got lost in transit. I wrote two emails as I saw on my account that they credited the one item, the other two items is still on order on my account. They refused to replaced the one item they credited because there is a price difference. The lost occurred from their side,so how fair is it that they want me to pay the increased price for a item that they lost. It is the 08th of October 2022 and I am still awaiting feedback as the consultants I spoke to is not knowledgeable about customer service and tell me when I requested to speak to a manager that the manager is going to tell me the same that I have to pay the higher price when the item was on special when I bought it. Till date I did not even receive anything from them and the communication is only one sided.
