Store of inconvenience!!

Store of inconvenience! Friday 24/03/2022 I bought a Kelvinator twin tub from Lewis Randfontein. I was tendered the amount of R3330 which was paid in full with the understanding that i will be delivered Saturday. Monday morning I had to my laundry by hand!! I received a call from the store manager claiming that I underpaid R500 on the machine, as the floor price was R3800. I agreed that they made an calculation error and I will pay the amount, on delivery of the machine. either I made the payment via EFT or they bring a machine, wrapped in card machine with as I have already been inconvenienced enough. Not only was delivery not on time, there was an incorrect tender?? I have made numerous calls this morning to the customer complaints line without results or answer. Calls were made to the store and no answer. I have also submitted an email to this effect to the customer complaints line. I wish for them to delivery the machine ASAP, and I will pay the outstanding amount via EFT or card machine.
