BAD SERVICE FROM THE ONLINE STORE SERVICE

I dont even know where to start where to start, on the 02/04/2024 our CFO made payment to Decofurn account but made a mistake intead of writing an ordeer number she wrote our business name, fine i understand its mistake fro m our side but i immediately recetified it and did a new order and sent an email with a new order. there was silence from the store, i contact them using my time and airtime they responded saying my order has expired i must place a new order fine i cooperated i did a new order number, again silence i contacted them again bear in mind i am using facebook messenger and email so that my message someone must atleast see it. yesterday i called and ask then a consultant by the name Cherry called and said i must place a new order this is the third time now, i am getting annoyed but i placed it again but this time now items that i want some prices have increased and the discount code has expired remember i paid R10 000.00 thats not change its a huge amount. now Decofurn is sitting with my money Cherry said she will come back to me not that i was expecting it but no one is calling even today so i am not sure if i should call the store again or request my full refund and the store must know i will need all items with the same price i first saw it. i need my delivery ASAP. its been a month now going back and forth with the store PLEASE GET ME MY OFFICE FURNITURE I AM EXTREMELY FRUSTRATED
