Bad experience with online store

I went in store to buy and fit a ring that I saw online. The lady could not find a ring that looks like it and wanted to find the barcode, but the site was really slow on both my phone and the store computer. After finally getting the code she said it's only in stock at HQ in Johannesburg and will need to wait 3 weeks to get it to the store.

I then decided to order it online. I could not select the size on there but I left instructions to get it in my size. I really hope they deliver the right size. Right after making the purchase, the confirmation screen shows a coupon code for 10% off first order.

Overall a very bad experience online.

1) Site very slow while I was at shop 2) can't select size 3) only get told about coupon dit first order AFTER my first order!
