New phone repair, Month without a phone.

I recently got a samsung A53 phone 2 months ago on contract as my company pays a cellphone allowance to be able to do my job as a technician. I called my network provider and they said call samsung. Samsung then told me to call another company. That company then said call samsung. Regardless I decide to go to Samsung in East Gate Mall. The gentleman helping me told me it will take 2 weeks to repair my phone. I told him I need a phone to do my job. He said he cannot help for that. Its their procedure and they have no loan phones. While assisting me he was using his phone and did not even look at me while talking. Regardless I gave my phone in and filled in the paperwork. This was Saturday the 19th of November 2022. Today on the 22nd of November 2022 I get a call stating that the parts to repair my phone will only be available in the next 2 - 3 weeks so I would need to wait till then and then another week to fix my phone. I said to the lady I need a loan phone or anything to be able to do my job. She said she is sorry for the inconvenience but they dont have a loan phone. What boggles my mind is that the phone is new (2 months old) and a cellphone retail store has no phones. None, not even a cheap phone to assist me. Considering the phone is so new, I feel like I am being reasonable not asking for a new one considering the gentleman at the store told me its a known problem on the A53 that the phone freezes and restarts constantly. The lady that called then said I can collect my phone that switches off and restarts and use it in the meantime till the part arrives and then I can bring it back. I am honestly going to see what my rights are regarding this because I will still be paying for a month of not even having the phone. Its actually insulting that it has become the person that paid for the phone to be making a plan to work and earn an income.
