FNB Connect - Selling Products under False Pretense's

I took out a contract with FNB connect on 31 July 2020 . The description of my invoice and agreement read as follows : Samsung : A31 128gb + Free Samsung Galaxy Buds+ Valued At R2999 + Top Up . I received the phone 3 days later and was advised to go onto the Samsung Members platform to get my buds , which i happily did only to be advised i need a invoice in order to claim the buds . I then contacted Customers services several times and got cut off every time . I eventually got through and was told to contact sales which i did and they referred me back to Customer Care . I then decided on 3 September to just add the Quote as i have not gotten the invoice yet from FNB and i only had till the 7 Sep to claim as per the mail i received from the Sales Consultant i bought the phone with Only to be told by Samsung that the Promotion is no longer running and i cant get my buds . I am still waiting for someone from FNB to get back to me on this after i have sent numerous emails .

To make things worse this morning the phone just stopped working - the one moment it was working and fine and the next the screen is stuck . To make things worse i paid this account up in full and now feel i want to cancel the contract , give the device back and be refunded as i bought the package with the buds included so feel i bought the package on false pretense's seeing that i never received the buds and the phone broke after 2 months . I will now have to seek legal advice as i really have no confidence in FNB connect left . The communication and customer service is appalling .
