Tupperware never deliver what you ordered

Hi My mother is a distributor for Tupperware She ordered on mobi there was a 1 day only special at Tupperware Order went through while there was stock now on collection she gets half n told the rest is out of stock Mind you this is definitely not the first time this happens....we tried to contact them and enquire because our customers are waiting for their orders No response They sometimes send something different from what you ordered without notifying you

This is the worst experience ever and definitely quit selling it .
