Online shopping = False advertising

I recently bought wine online at PnP online (Order #***6). When I ordered my wine it gave me a total cart of R1311.20 (as is shown on my online shopping profile). When my invoice came, I was charged R1644.00 and subsequently deducted from my credit card. After contacting PnP online shopping customer care THREE times, they told me they will investigate the matter, only to be notified that a refund of R92 has been processed, leaving me with R240.08 that I STILL HAVE NOT RECEIVED A REFUND FOR and was overcharged.

This is FALSE advertising by PnP Online Shopping and I would not recommend anyone to EVER buy online at PnP. There are other businesses that would much rather appreciate my support. How can you advertise a price, let me check out at that said price, and still charge me R332.80 MORE??

If this matter is not resolved, I will have to contact the Ombudsman. I am utterly disappointed in PnP Online shopping!
