Unresolved Shipping Issues with Samsung Dealer

Hello, I am writing to address a new problem regarding a previous complaint that was not finalized.

Initially, I requested the shipment of my products. However, due to unforeseen circumstances, a family member who was supposed to be home was unable to be there. I asked to cancel the shipment that day. The shipment was not yet uploaded, and I was directed to Samsung customer service to cancel it, which I did.

When I later contacted customer service to reschedule the shipment, they informed me that I needed to arrange it with the dealer from whom I purchased the products. I called the Zirve Group Samsung dealer on Alemdağ Caddesi/Ümraniye to set up a new shipping date and asked if June 20th was available. The person I spoke to said he would check and get back to me. However, a different person called back and informed me that the second shipment would cost 900₺ per product. They also said I should have informed them about my cancellation.

I followed the instructions given to me and was not informed that I needed to call the dealer to cancel. Additionally, I do not recall signing a contract stating that a fee would be charged for a second shipment if no information was provided. If such a contract exists, please show it to me.

I became very frustrated and ended the call abruptly to avoid further conflict. As someone who is married and in debt, 900₺ may not be much for others, but it puts me in a difficult situation financially.

Here are my questions:

Do we have a contract stating that a fee will be charged if shipping information is not provided? The only document I signed is the one related to this purchase.
What will happen to my products if I cannot pay the fee?
Can I return the products? If these devices malfunction, I will face additional hardships.

I hope this issue can be resolved promptly. Thank you for your attention.

Kind regards,
