Poor Service and being treated like an Idiot

I went to the store I wanted to purchase a swimsuit a size 34 to 44 had a price tag that said R229.00 and 38 had no price and when I got to the till It says R299.00 Crisky apparently shes the store manager and anothe guy who is a manger said he doesnt know her surname and he knows it I was being treated like an Idiot and she had the audacity to tell me its not the same product that one was from last year I said I was at the shop a few days they didnt have those swisuits and they are the exact same size and design and she basically refused for me to buy it at R229.00 and she had the nerve to say I take it or leave it I told her I am not a fool how can I buy a size 38 for a higher price yet sizes higher 40+ are exactly the same Ackerman's employees make rules they see fit I am fuming and how they inconvenience me is such a stupid manner to make matters when I call their call center they said the supervisor will call me its even 19h00 still no call I wanted thar product today. I AM LIVID I am even thinking to close this account there is always something with Ackerman's Wonderpark. The service was disgusting.
