No Delivery or service

I am not really someone who complains about Suppliers, but this is ridiculous!!! My original order was placed on the 15th of May if I can remember correctly. After a while I have contacted their offices to follow up on my order whereby the lady told my it will be send out the following day. Before contacting their offices, i have send quite a view mails to confirm that my order has been received and to follow up, whereby I have not received any response. About a day or two later (after my phone call), I received a mail stating that they are out of stock and will only receive it on the 01st of June. When i placed the add, they have not put up a out of stock sign. On the 1st of June, I contacted again to follow up if they received the boots, whereby they did not. The consultant said he was going to try something and see if he can speed up the process. I had to give it 5days. After 5days, I contacted again whereby the consultant told me that my order has been cancelled and a new one was made on the 1st of June. She also confirmed that the boots was not received. Now I am asking...is there any one following up my boots and how long do I still have to wait? I am an existing client !!!!
