Game under hand tactics

I have ordered Huggies gold nappies on the 31st July 22 online. No update no delivery of the parcel. Today (08/08/22) I did follow up on day 8 after ordering, am told the item is out of stock and I asked for refund because I really needs diapers for my baby, am told I must wait for 7 to 14 working days to be exact (23/08/22) for refund back to my bank card. Am desperate because the nappies are finished I do not have money to go buy no w while waiting for the refund.

What makes the matters worse is the fact that I can not talk to the supervisor or the manager to assist with this matter. There was no update from the shop since the item was out of stock. How possible is it that I could pay for an item that is out of stock online? Am being disadvantaged here this shop is really taking me for a ride. I need my money back today I can not afford to wait while my baby do not have nappies. I can not be told by policies that suit the shop while the same shop failed to let me know know the item I have ordered is out of stock on time or before I could make a follow up or make in inquiry my self.

Please assist I really need this cash for the nappies
