Worst S10 upgrade / bundle experience

On Saturday the 23th of Feb I made my way to Vodacom Tygervalley Data store to pre-order the latest Samsung s10 prism white 128gb with the wireless earbud bundle and upgrade my existing contact . I was told that they unfortunately don't have stock of the phone and that ill have to "pre-order" the phone in order for me to acquire the deal with the wireless earbuds. The representative only took down my details on a draft sms on his personal cellphone. Yesterday ( 25th Feb ) I went to the store again to check on stock availibilty only to be told that they did have the s10+ bundle but its unfortunately sold out which I understood, I then asked the Vodacom representative to please take down my details in order for me to pre-order the device again only for it to be written down in a notebook. Today the 26th Feb I went to the store again in order to find out any clear ETA on stock and if I pre-ordered it (like I already did twice) would I get the wireless earbuds with only to be told that all the units with the earbud bundle have already been sold to other clients that also pre-ordered and that he is sorry. Now I need to find out why exactly do I need to pre-order or keep my business with Vodacom if you're anyway not going to even let me, the client, know if the stock is available or even attempt to assist me. I have been a Vodacom client for 10 years now and am seriously considering terminating my contract.
