Rude service - Consumer Complaint for PEP STORES

Hi I bought a comfort at pep home for queen size it's smaller then the rest of the comforts that I bought there Before, the new one doesn't even fit on the bed and now my granny took it back they told her they can't get it because it's open and they won't be able to sell it, but how would I have known that the queen size I bought won't fit on the bed when I have 2 that I bought first in 2017 and another last year November and both fit properly but the one I bought now it's smaller and fits for a double bed. Please note they were very rude towards my granny and they were speaking there own languages shangani and Venda shouting at her in front of her as if she's a stupid in so angry
