Bad customer service and misleading information

I ordered my router and sim on 28 November 2022. And today (08 December 2022) it still haven’t been delivered. On 6 December 2022 I asked them to let someone sign for me as i am working during their delivery hours and phones are not allowed at my workplace because of the nature of the work we do. They then said they can deliver during the hours that i am available. I said 7 pm and they said its fine. Today i called and they said they don’t deliver after 4pm. They must just tell me to cancel the order if they don’t want to sell me their products than to waste my time.
