DISAPOINTED CUSTOMER !!!!

I upgraded my contract via telecom 7 May 2020 , for the P30 Lite 2020 , I confirmed with the agent if they have stock available and was advised they indeed have stock, and will receive delivery in 3-5 working days , Today I called in to find out my tracking number, only to be told my Order is on Back order due to No stock, Eta for stock is 15th May, its 8th May today , so basically im only going to receive my device maybe after 6 working days (if stock comes in) ! is this how Vodacom works ? is it right for staff to mislead customers in order to make a sale ? despite calls being recorded !! I am really disappointed as this has not happened to me with any other Network
