ADIDAS SOUTH AFRICA ONLINE - REALLY POOR SERVICE

Purchase a golf shoe ONLINE - 14/06/19 - received shoe 21/06/19 but size was too big. Logged an exchange request 24/06/2019 - was informed by AMIR that he had reserved size 8 for the exchange and that item will be collected within 2 days - item was collected 4 days after call (28/06/19). Called ADIDAS ONLINE numerous times the following to track the return which was only captured by 08/07/19. I was assured by Julia that the replacement shoe will be despatched by Tuesday 09/07/19 and delivered by 10/07/19 as I am leaving for golf trip 11/07/19. Today - 10/07/19 I am now informed that there is actually no stock of the size 8 and the exchange cannot be done - After been assured that the replacement shoe was reserved it has taken ADIDAS SOUTH AFRICA ONLINE two weeks to realise that they cannot honour the exchange - THIS IS EXTREMELY POOR AND DISAPPOINTING!!!! I could have saved all my take making calls to expedite poor service!
