Debit from prior owner? - Refer 465 296 18

Imagine my surprise when my new rates account - instead of showing a credit (as per last account received 04/05/2015) - had a large debt (R 3346.19). The prior invoice dated 05/06/2015 - which of course I never received (I get accounts emailed!) - had a sundry IINTER ACCOUNT DEBIT of R2070.24 exc VAT. Rather large unexplained debit I would say.<br> I phoned your call line - nightmare to get through - Helene Bam told me an adjustment from Mr James Davie (account number ***) was done. That's not me, why has it been transferred to me, call reference ***8.<br> I wrote to your accounts department - nothing back from them.<br> I am not sure how this was transferred from a previous owner into my outstanding balance? This lady thought it was fine, gave me a reference number for me to sort it out
