incorrect bra cup sizes

very disappointed with the quality of Ackermans bra cup sizes now as they seems to be incorrect or rejects. I was so happy and relieved when Ackermans came out with the bigger cups sizes at affordable prices and I have bought almost every six months since and last week Saturday I bought one set ( 2 bras size 44 E cup ) think it was R 240 get home my daughter 3 years pulls the prices off and throws it away and now I cant exchange it. The cup size is definitely incorrect and if definitely not a E cup as it fits a C cup lady and now I am stuck with bras that I cannot use because I don't have the tags on it.
