Wish complaint: Refund due to Delivery Date

I placed an order on the 6th October 2020 for 2 each of 3 items. The delivery date given at point of ordering was the 27th October. One of the products then changed to the 13th December which at first they refused to refund but have since done so.
I have since checked on the other 2 items, one is stating it will be delivered on the 26th October but the other is still processing! This will be coming from China, (as with the other goods) so if it hasn’t even been dispatched yet then I doubt it will be here before the beginning of November, which is when I desperately need the goods for, no good to me after that as will have to source them from elsewhere.
I have tried to speak to them on Customer Support with regards to cancelling the items that are still processing but they have changed the automated response to say I can’t cancel as it’s still ‘processing’and gives me absolutely no option to get in to any kind of dialogue with regards to it! I’ve also tried calling 2 numbers that I found but no-one answered.
They refused to cancel the first item because they said it had already been dispatched so I stated that it was unacceptable as they had taken my money under false pretence! I then woke up to an email the following day to say it had been cancelled and the money for the part of the order that had been moved to the 13th December had been refunded.
They are asking me to wait until the 18th October before contacting them, i cannot do this. as explained I need these products for the beginning of November. There is only 1 other place that can deliver them by the end of this month nut I need to order it today!
