False advertising by Pick n pay black friday special

I purchased the black friday online special of 24 savanna plus an extra 6 for 324.00 on the 30 November 2020 and my order was delivered on the 4 December 2020 because Pick n pay delivery time till then was booked. I received my order on that Friday and only find out there was only 24 savanna packed , while the driver was there i called pick n pay and the consultant i spoke to told me they do not do re-deliveries they will refund me R90.00 and i refused the re-fund because i paid for the convinience of getting my product delivered to me and because there was that extra 6 pack that come with it. The consultant told me they will look into the matter or i can go to any pick n pay store to fetch the 6 pack i told the consultant that if i can go to the store to get the 6 pack then i could have gone to buy my drinks instead of ordering online. Today i received a refund of the R90 regardless of the fact that i said i do not want a refund and i called pick n pay and asked if this is how they resolved my problem by giving me what i did not want and was told yes this is how my complaint was solved because they cannot re-deliver , i asked to speak to the manager and was told they are busy on a call and will call me back today and till now i have not received their call. The service i received was horrible and Pick n pay made the mistake with my drinks and basically told me so what just take a re-fund and move on ,we messed up hour order and we are not willing to go out of our way to fix it because we dont re-deliver .Poor service indeed which unacceptable because now i think it was false advertising they did not have the special that they advertised and decided i will get a re-fund
