Techinn Poor Customer Service

The worst service from an online store!!!!!! I purchased an item on the 5th of May 2022 and to date cannot receive information on this purchase, other than, the item is on transport to the country of destination (which is dated 11th May). So acording to Techinn, so long as the item has been shipped, I am unable to cancel this order. Intheir last correspondence to me, apparently the transport company is requesting me to fill in paperwork, to proceed with my claim. This is laughable. I infact DID not do business with the transport company but with Techinn, it is solely their responsibility to make followups, fill in paperwork and do whatever is necessary to resolve this claim. All I request is a refund, clearly they have no means to track their own shipments, they lack the professionalism to handle sales delays and they shifting responsibility to the transport company, whom they do business with. I didnt engage a transport company, I purchased from Techinn! They need to refund me asap.
