Poor Customer Service by Garmin SA

I paid R1 396,56 for a repair replacement of an Approach S Black golf watch on 25 July 22. Delivery was promised on 27 July 22. The item was not delivered as promised on 27 July 22. I telephonically enquired with Garmin SA on 3 Aug 22 why delivery did not take place on 27 July 22 and Thsipiso apologised and promised delivery on 5 Aug which also did not happen. On 10 Aug I personally went to Garmon SA's offices in Rosebank where Mornè apologised and promised delivery on 12 Aug 22. Sadly nothing was delivered on 12 Aug 22. I honestly dont know what else I can do to expedite delivery. Garmin SA simply make the one promise after the other and dont deliver. Refer Garmin SA reference number 139219
