Lacoste Online - Shocking Customer Service Levels for a High End Brand

I made an online purchase with Lacoste.co.za, only to realise that it was an incorrect size, however I checked with a store in Cape Town, and they had the correct size.Called Lacoste online immediately and spoke Tebogo to stop the delivery of the incorrect size lacoste item, and to rather for the sake of efficiency, I could collect the correct size item in-store. The arrogant and rude Lacoste Employee Tebogo informed me that this will not happen, and I must wait for my online order to be delivered to me up to five working days, and only then can I take the item in-store for exchange. I informed him that the item is already paid for and it is merely an exchange within the Lacoste retail framework in SA. He adamantly refused and informed that he is the Lacoste Warehouse Manager and this is how it works and I must just accept it.I requested to speak to his manager, he informed that his manager Micaela is off sick, and that I can only talk to him in her absence. I asked him what is difference if he delivers my item to the store or to my address, Tebogo informed that if it is delivered to the store it could be ****** and therefore it must be delivered directly to me. I found this response absolutely absurd, and not appropriate for public knowledge.I then called Lacoste Head office and spoke to Gugushele, who was very pleasant. I explained my situation with Tebogo, and she informed that this can be done by merely providing a credit note, as this is what they do on the Levisons retail framework. She then informed that Tebogo reports to Micaela, unfortunately off sick, but Harifa the Lacoste Manager can assist. She then informed that she will call Hariffa and request her to return my call. I waited for two hours, not receiving Hariffa’s call, I called Gugushele again, who informed me that Hariffa is liaising with Tebogo in my matter and he will definitely return my call. 4 hours later not heard a thing from either Tebogo or the Lacoste Operations Manager Hariffa. I must admit that Lacoste being a High End International Brand, this is the worst kind of customer service that a customer could receive.
