Disappointed Customer

On Monday 17 December I went to Woolworths Greenstone Mall to do shopping for my little one on the way and spent over R3000. One of the items that I bought was a bikini bottom which was initially R200 but was marked down to R120. This mark down was done in a red pen. When I got to the counter the lady that was assisting me scanned to bottom then called her manager Desree whom we waited for for a while ( overhead one of the colleagues actually saying she is on WhatsApp but cant come to help) when she got there she said the item was not on special and that I had to pay the full price. I said to her there must be something wrong because there are more items on the floor marked down the same way. She was not sympathetic at all and had a bit of attitude. So I said to her fine I will pay but I want her to give the tag that was written the mark down amount she refused and caused a scene. So I took a picture of the price and proceeded to pay the full amount. Now that service I do not expect from Woolworths of all the stores that I shop at and you can have a look at my profile I do a lot of shopping at woolies. Now my issue is not the price but the manner in which my complaint was handled. I'm so disappointed and please repremand this lady she must take her job and customers seriously.
