Requested an RMA for a faulty SB-RKTQ-8TB drive with Sabrent and they have been messing me about for 5 months. They have already approved the return but won't provide an RMA number or a replacement because they apparently don't have stock. I've been emailing them every couple of weeks to no avail; In the meantime this £1500 drive is sat there gathering dust.
What can I do to resolve this issue, since there doesn't appear to be a complaints process?
