Ordered 3x LEDs from Hinterfeld, they sent me out 1, then they seemingly closed their business temporary. Its been a month now, without refunded me the money, £70, for the two unsent LEDs. Now Hinterfeld has closed all methods of contacting them and failed to respond to all my message before it did. I'm concerned about my money, I've never dealt with a company so unprofessional, claiming to be trying to get a new warehouse though no interest in keeping current customers happy, interesting technique. Shall i be contacting my bank to try and get the whole transfer reversed?
