20 days later still waiting for my delivery?

I have placed an order on the 17th January 2024 even today, the 5th of February 2024 I am still waiting. I am not sure I should 9 months or what. I have called their support centre and they said they will get back to me, that has never happened. I then proceeded to log a ticket on their website, still no response other than giving me a ticket number .Mind you my money was taken. I am done buying books through them.
