Payment issue

I went to Andiccio24 Randburg on the 13th of October. When I swiped, money came out of my account but on their speed point it declined so I showed them that the money came out but they insisted I pay again. They said they will investigate and call me, when they called they asked that I send my banking statement when that was done they said I should wait for 7 days so it can clear on their side. I kept on calling after that 7 days but until today which is the 04th of November am still wait for my money to be sent back to me.
