Non delivery nor refund of money.

Ordered a 3/4 Serta mattress and mattress protector on the 05/01/2024. The Mattress Warehouse has not been able to supply ordered mattress and protector. I cancelled order on the 31/01/2024 and have been promised a refund ever since then. Brendon and Future of the Midrand branch have been promising and promising, but nothing to date has materialised. No refund and it is 22 days since cancellation. We are pensioners and can not afford to lose any money due to non delivery and/or false advertising. Urgent intervention is needed.
