Bad Customer Experience from Crocs Online

So, I place an online order on the Crocs website and receive all pairs of shoes quick, quick!!. Great "live chat" functionality so by the way!! It's actually a live chat with a real person on the other end!!! But, try to get it exchanged for bigger sizes, and the real drama starts!!!! On 05 Dec, I send a mail to start the collection and replacement process. no feedback until the 12th!! Here they say they will arrange a pick up... This only happens on the 19th, which is now 2 weeks after the first communication. remember only 1 public holiday in this timeframe and oh yes, their staff party!!! On 24 Dec I finally receive the tracking number for the 1 pair of shoes, that's coming from Jo'burg… Yeeha!!… Only to arrive today.... It the WRONG SHOES!!!!!! Not at all what I ordered... Remember, I only wanted 1 size up in each of the replacements!!! I call the online support this morning, I am first in the queue at 08.10.... only to hold on for 15 MINUTES!!! They cannot confirm or deny that the other 2 replacement pairs have left the warehouse..... If you cannot give me a tracking number,,, then it was not picked!!! I know that!!! Just say so!!! So, I paid for 3 pairs of shoes. I am sitting with one pair that I do not want, and I must go see if Access Park Store will give me an exchange because this could also not be confirmed (we will phone ahead mam and they will be waiting for you.... yeah right... ) I do not know when I will receive the two other pairs that I have paid for, and I cannot get a credit to my account so that I order what is currently on the website... (sorry mam, I cannot confirm that as my Supervisor is not available) I will never shop online with them again... Very poor customer experience!!! I was more than patient and accepted the excuses today alone from all three staff members I spoke to... But enough already... VERY POOR SERVICE FROM SUCH A GREAT SHOE BRAND!!!! VERY DISSAPOINTED.....
