I placed an order for 4 batteries on April 6, 2022 (***** ************). The batteries were a normally stocked item, but they were out of stock at that time (I had previously purchased 8 of the same batteries, which had been listed on their website). I was informed that the batteries were already on order from *****, and the lead time was 2 months (end of May).As of the beginning of September ****************************************************** ******. During this 5-month wait, I had some major issues with the first set of batteries. As a result I decided to cancel the order for the 4 additional batteries and requested a refund on September 3, 2022.This was part of their response on September 19: "We can refund less a restocking fee once we are able to resell to another person. That *** take a few months, since we won't have them in our warehouse for at least 90 days. The standard policy for these batteries is a non-refundable payment as we have had to order these in from the manufacturer and we are out of pocket for months while we wait for production and shipping. We will provide you with a refund, but please bear with us as we have to wait for the inventory to arrive."Since the batteries were a normally-stocked item, these comments make no sense, but they did offer the refund.They replied with much the same response on October 11. Since then, I have emailed them on October 12, 2022, February 20, 2023, and May 1, requesting updates and reiterating my request for a refund. On June 19, 2023, I sent a final email, and followed it with a registered letter, which was received.To date I have still not been told what their restocking fee is. Given that the batteries remained undelivered at the time of cancellation 5 months after the order was placed, I don't believe any restocking charge was justified, but in the interest of closing this issue, I told them I would accept a 5% deduction of the refund. There has still been no further response from Azimuth.
