Mistake on Order

I am an account holder at Justine cosmetics products, so November 2015 I placed an online order on the Justine website, mistakenly I punched in a wrong number of brochures which I only realised on the day of delivery.<br> <br> I do not sell Justine and do use the account for my personal use only, the brochures ordered were 125 which sumed upto R472,96. I called Justine contact centre for assistance in enquiring about the procedure to have the brochures returned as I had no use of such a huge number.<br> <br> I was told by the consultant that because I have made the order personally I cannot be assisted. I then emailed address which I constantly use when need assistance and do get responses, but not this time.<br> <br> I awaited response for atleast 7working days as it states , up to this day. Amazing enough January 2016 I received an MMS of a letter from ICT in connection with my payment, now how do I get to pay on time when I had a dispute which was never attended to? I've had an account with Justine for quiet a while and have kept my account to date.<br> <br> Now my concern is with Justine as a customer am I not allowe to make mistakes? Is this how they treat their customers?
