MY MONEY PENDING?????

On the 02nd January 2016 i went to Shoprite to withdraw money and I was told it has declined due to network error.Within few minutes i received a message that I withdrew R1000 which I never received. I went to Shoprite to ask what happened and told me its not showing on their side i have to contact my bank. The branch in Malamulele told me i must get a receipt from Shoprite which I never received as the transaction was declined according to them.I was told to fill a dispute form which I did and was told i will access my money with 48hours even today I'm still waiting. On my statement it shows pending authorisation. Can someone assist me urgently..
