Makro online purchase ref nr MAK3122932. I purchased a tumbledryer 29 Jul and before it was dispatched for delivery, the order was cancelled. Despite the cancellation, it was still delivered 10 Aug. We arranged to have it collected again to return the dryer. It took more than 2 weeks to collect (23 Aug). I still await my refund and it is now 21 Aug. I have called and emailed numerous times without success. What should I do to get my money back?
