Unsatisfactory service

I ordered and paid for textbooks on the 19th Dec 2024 and send the PoP. Later received an sms that the books have been delivered went to school and I was told ,there are no textbooks that have been delivered. I took it upon myself to follow up and called I didn’t like the way I was spoken to. I was told that the books will be delivered before Friday. I haven’t received any communication yet. The student is new and she’s struggling with her studies as she needs the textbooks to guide her especially with her homeworks.
