Still waiting for new TV after empty promises

Ref number TJ***. Still awaiting the new TV since the damaged TV can't be repaired and this was already reported on the 7/11/2022. Hisense already credited Teljoy, (I received a Whatsapp with the letter from Hisense) since the TV was under a maintenance plan, this process was approved. The damaged TV was already delivered back to my home 2 weeks ago. I got a call stating after 24 hours after the credit was received then a new TV will be delivered to me. That was two weeks ago and nothing happened. Then I got another phonecall from Teljoy stating the new TV was approved for me since the old TV cant be repaired and is under a maintenance plan and Will definitely be delivered within 5-7 days. This didn't happen again. Very frustrating process. I asked Teljoy on Facebook what's going on and it was stated to me there is no stock. Every time I have questions there is another excuse. If there is no Hisense 55inch then send a Skyworth 55inch. Already the second debit order was deducted for a maintenance plan on a TV that can't be repaired. Teljoy can you please do something about this, it can't take this long.
