Contraindication to communication sent.

How do you send a client an email and contraindicate yourself on a telephone call. Ie " If you do not pay your contributions for two months, or on the date agreed with us, we will cancel your membership." nowhere in this statement does it say that you will double deduct. Loyalty means nothing to this so called number "1" medical aid company. We have been loyal to them for more than 7 years. Be careful to speak to any of their call centre agents or team leader they become aggressive if you point out their contraindication.

I hope they call to discuss matter and try and save a loyal client.
