Unhappy customer

On November I made an online purchase with the request that it be delivered for collection at Carnival Mall shop. To this day I have not recieved the shoes that I bought. I am not happy at all. I have done to to make a follow up to no avail. On December 1, I called Head quarters *** to make a follow up, but they transfered my call to the online department -three time and no one responded in all these occassions. on Thursday Decembe 3, I called again and I was not helped, instead I was given another number to call ***which I was told is Tread and Miller.. and when I called the lady told me the shoe has not been delivered. Infact she said she doesn't know what is happening with the delivery and promised to return to me the following- well I'm still waiting and she has'nt returned. So as things stand, I still don't have the shoe, nor do I have a response from Cape Union.
