Appalling service from Garmin SA Store in Rosebank

The Garmin products are great, but their service at the SA store in Rosebank is absolutely pathetic. I ordered and paid for a watch last Tuesday, and did not receive any acknowledgment of the order or payment. I queried this yesterday, and they asked me for the order number, which I gave, and then they asked for proof of payment, which I gave. I would have thought they keep a record of orders and receipt of payments, and it should have been really easy to look up my order, and then check payments: clearly way too much work for the employees. And since I furnished these documents, I have been ignored. I have asked for an update to at least advise me of the status of my order, but the employees couldn't be bothered to respond. Clearly the store is mismanaged, as any manager worth his/her status as a manager, would not tolerate such incompetence: the employees should be dismissed for such gross poor performance. Now I remember why I have bought my previous products from stores overseas: they actually understand what it is to offer a customer service. I had forgotten my previous experience with Garmin in this country..!! And that was years ago: nothing has changed...
