Vodacom online *****

I'm extremely frustrated with what has happened at Vodacom. On the 25th I had a debt order go off my account I reversed it because I don't have any account with Vodacom. Again on the 26th another debit went off. I went into the branch and I was told 2 contracts were taken on my name this month and it was done online. I don't know what documents were used and where they got my account from because I didn't approve any Debi check mandate for the debit order. I've worked very hard to maintain a good credit record for something like this to happen. I need this to be sorted out ASAP. the store associated didn't want to tell me where the devices were delivered to.
