This i only found out the next day when i tried to rectify another fault on their side Santam side my addres detail they entered wrong and after receiving the new documentation of my new vehicle with the correct addres i found out my instalment DOUBLED up along the way ..how pathetic can it get after logging calls and phoning about R60 airtime out still no answers ..then days later a respond, they listend to the recorded calls and also notify my that Their consultant as per email to me gave me the wrong instalment and that the instalment as per last email to me wich is doubled is the instalment i will have to pay monthly ...Can you even believe your ears i was astonished cant believe the unprofessional services they delivered...
