Reebok'se service isn't up to standard

I place an online order on 21/2/2015. According to the website the shoe and required size was available. Got an email on 23/2 to say that the size wasn't available any more. On 1/3 I requested feedback on my order. On 2/3 Jo-Anne rep**** that she is still waiting for the department to reply. On 11/3 I once again requested feedback. On 12/3 Jo-Anne rep**** that they found the product and that it was dispatched.12/3 I requested confirmation that it was sent. On 13/3 I got this reply: It will be for the latest Tuesday, 17/03/2015 before end of working day. 17/3 Yes, herewith direct number for supaswift team and waybill tracking number: Fedex Supaswift: ***Tracking number: RB*** According to the Fedex website there is no such waybill. Today Kathy rep****: I have requested a waybill from the store who was earmarked to have your parcel delivered to you. I am awaiting feedback from them.<br> Please help me to get the shoes that I paid for.
