Dis-chem online - Not Impressed with my First Online Purchase

I did my first purchase at dis-chem online on black friday. purchased a philips electric mens shaver. it arrived yesterday the seal on the box has been opened. i do not want to purchase electronic items where the factory seal has been opened. i just called dis-chem # provided on the email order, then had to call the dis-chem online number, waited 8 mins. was told by your consultant that i must take back to a branch, which i refused, as its an online purchase. she said the branch that sent (oakdene) will call me. i then asked that the item must be replaced for a seal boxed, she said she does not know if they will exchange.
