Orders getting lost, mixed up and never shipped

I ordered a leotard from the Turning Point (TP) online store and initially, I received excellent service, with them ensuring that my order was delivered on time for my dance exam. This was, however, a leotard made with poor workmanship as it was skew and the lining was a material that had no stretch, and I had to make do with what I had for my exam. The second problem that occurred with this company, was that a teeny tiny white leotard was delivered to me the next day, even though the invoice was made out to someone in a different province. I sent photos of my skew leotard and notified them of the incorrect order that I received. They sent the courier to pick up both pieces and I handed the courier a closed bag with both garments in. Some time had passed, when I got a call from TP asking if I sent the white leotard back, because their client have not received their order. This was very unprofessional, as I sent it back and the fact that the client did not receive it, had nothing to do with me. Fast forward some more, I received an email that my order has been shipped. It took me more than two weeks of emails, Facebook messages, Facebook comments (as you cannot write a review on their page), a tagged Facebook post and phone calls to receive my order. It was only when I started to email the CEO and setting an ultimatum that I wanted a refund if I did not receive my parcel in two days, that I got a response. Turns out that in the two weeks since I received the email that my order has been shipped, it was sitting in their store the whole time and it was never shipped. They did send me a dance bag as an apology, but at this stage, I do not think that I will order from them again.
