Baby Leo Electric breast pump

I bought the item after l was assured by Buhle (salesperson) in Aeroport that the product has NEVER HAD ANY RETURNS. I found two of the 16 items missing in the package. Upon return to the shop to complain a sales guy told me about the returns they have had on the MISSING items. Being a breast pump, it is not returnable and now l have to BUY separate extra products to supplement the use of the pump. All I need is a discount or voucher to but these complementing product so that l can enjoy & use the pump and accessories!
