Feeling cheated and denied from such a big medical aid

Very bad service rendered and hell bent on ruining people financially. After my family and I were suspended for not paying on time or actually for funds not reflecting in my account, after I tried to get the details from anyone the banking details to make the payment on the 3rd of april, all efforts made to discovery from my end failed. Then I get suspended immediately so no cover the whole month of April and then they have the cheek to send me an sms they will be deducting the money from my account on the 2nd of May. This is brought day light and not medical care but exploitation in my eyes. I have 2 young kids and rent to pay and I just lost my dad recently. All my emails are falling on deaf ears. Please somebody help me and I pray that these greedy money grabbers don't interfere with my bank account because of no service was rendered for this whole month, one should not be charged. Please Discovery don't rob my children of the little we have. Life is very hard as it is.
