Terrible service at Minigood shop based at Cedar Square

By purchasing led light at minigood. at home after assemble, I realized that it is not very good quality. I brought the return within 7 days. The owner refused to return the money referring to the policy, where, by the way, nothing says no cash refund. They kept me in the shop almost for one hour. The owner was very rude and loud. Motivating that on the slip says no cash refund. But before I paid, I asked about a refund and read the policy, where nothing is said about it, only after receiving money from me they gave me a slip, where it said no cash refund. And also, when I brought it back, the staff confirmed that this lamp does not hold the phone tightly and during the inspection they broke the fasteners. And after all, it turned out that there is nothing to change for, they have no stock . After all this, the owner said that I could buy something else for the same amount, or I should wait for the new stock. What I don't want to do. Once again, he was so rude and annoyed, he also confirmed that I can go anywhere with a complaint, he does not care.
