Terrible Service, Incompetence, Harassing Sales Calls

Placed orders online for a total of 4 blankets. Two of them were on a sale save 300 when you buy 2 and I thought we got a bargain. On checkout we got the discount on the items that were for sale and then app**** the voucher code for a further R250 off. The original price was around 1900 and because of the special it dropped and the voucher it dropped to about R1300 and it was successful online. To my surprise i received an sms indicating that I should pay R798 to get the other blankets but the transaction was successful online. They told me its because i purchased on another profile, so lets say i remove the R250 and we pay the R250 voucher why am i paying for the blankets that were on special? Someone is *********** and I feel this is *****ery and a breach of the CPA and on top of this they don't stop calling us "DO YOU WANT TO ORDER". Everyday the sales agents are calling us to ask if we want to order. WE DID ORDER. STOP HARASSING US AND FIX MY ORDER. i tried calling the call center the worst service ever, we cant speak to a supervisor coz of corona then i asked to be transferred to one, they say they cant. Then i asked if I can get the extension number or number i can call them on and they can. Today they brought delivery and returned it back as I cannot accept this kind cunning business that HomeChoice is running. They just don't care, once they have your money then they just don't care. I HAVE THE PROOF OF THE TRANSACTIONS!!
