Unhappy Customer

I placed an order on the 13th of December 2020 and made an online payment of R2600 everything was processed and I received a notification stating that my order is in progress, then on the 14th of December 2020 I received a phone call stating that the store that I had chosen to collect my order at it currently not in operation because it's a new store and they were supposed to have moved in on the 07th of December 2020 but they haven't and they are unsure when they will and that they are unable to process my order. I am required to wait until the store opens of which they are also unsure on when that will be, so my question is why was I allowed to place an order at a store that is not yet operating? and if I say I want to be refunded I am being told that It will take 7-10 working days before I get my refund and I need these items urgently that's why I even opted to collect them myself instead of scheduling a delivery. I am very upset with the level of service and ********* conduct of this store and request immediate assistance.
