Unknown "bill payments" deducted

My visit to Pretoria central corner queens street and Madiba street today at 10h00 refers,

I visited this particular branch following numerous transaction between 22 - 23 May with reference "Bill payment" with amounts ranging 150-100 all calculated with roughly R750

The consultant insinuated that someone I know uses my account to make those transactions, which I insisted it was untrue,

She told me that nothing can be done except to open a ***** case, which might take sometime,

Am frustrated because my concerns where not considered as urgent as it should,

I trusted Capitec with my funds and the level of service received was not taken seriously,

Because of other pressing commitments on the day I left,

I would really appreciated if this matter can be attended to urgently as my money it's being deducted every minute
