Edgar's Mall of Africa,poor service, lies and lack of communication

I bought clothes using payjust now,money went out of my account and the payjust now app shows payment paid successfully however the store refused to give me the merchandise because "apparently the store didn't receive the money,i spoke to 4 people including the manager who showed me the response from payjustnow saying every has been processed and they need to release the goods,the manager still didn't release and had the guts to tell me that they will see what the can do 5days later, I want my goods or atleast money as this is just an inconvenience for me,i travelled far to go twice to the mall for this,the always promise to call me back and update,no one has ever called me
