Truworths online confirmed and paid order cancelled due to their system pricing issue.

I am actually LIVERD to say the least. Placed an online order for my desperately needed beauty products on 2 May 2020. Paid for it, awaiting delivery. Only to receive an sms from Truworths on Monday 4 May stating that my order was cancelled. I did an enquiry, to be told they had a system issue on pricing. I need to replace my order. Upon doing so, the exact same products increased in price at a total of R300. I re-ordered because I am in desperate need, but their system pricing issue is NOT my problem and if memory serves me right...according to CPA...what was advertised, is what I pay. All consultants I spoke to was very nonchalant. Furious to say the least.
