Discovery ends membership without my knowledge

I received an email from Discovery stating that my membership has been withdrawn. I had no idea of this and paid mt premium for March and April today. I work for the Department of education and received my salary for January and February in March and got paid short. I have an affidavit to this effect and my payslip with the payment date. Thus I had difficulty keeping up with payments. I have however paid my premiums for April and May today and wish to continue my membership with Discovery. It is disappointing that Discovery saw it fit to end my membership without so much as a phone call. Furthermore I have paid my premium for May so it is in actual fact ******* to cease my membership when I have paid for it.
