Annoying Courtesy Calls Woolies!!!

I have never ever missed a payment for my Woolies account but your harrasment coated as courtesy calls is beyond annoying. Your consultants are extremely rude and ill mannered. They completely ruin your brand's name. I don't want to be called for something that I always pay even before the due date and given attitude about it. I receive my bills and I have the app. Stop calling me for nonsense and put your energy towards calling people who actually need those courtesy calls!!!
