Bait and switch tactics

I ordered the Nokia 8 Sirocco on contract from Vodacom, went through the application process over the phone with agent LM_NTOZAKHEM who took down a bunch of personal details (Including banking details, I have the call recorded) and said that the device would be delivered in 1-2 weeks. I then received a vetting application email and an SMS saying that my application was successful. Tried following up on them with regards to delivery but I cannot get through to anyone that can assist. Vetting Reference Number: ********** 7, Customer care reference numbers: 003S~SCR4, 002L~6Z9E.
