Suspension after payment

On 26 November 2015 we paid our medical aid premium via EFT with the correct reference number. On 14 December 2015 we received an email and an sms that we have an outstanding debt, I forwarded the proof of payment on 15 December 2015. On 17 December we received an email and an sms that our medical aid is suspended. On the 18th we forwarded the proof of payment AGAIN and still nothing has happened, we are still suspended. After each email we just receive a reference number and then nothing at all! This can not go on! We pay a lot of money and then the payments aren't allocated and then we are suspended. My wife is 37 weeks pregnant, what do we do if she goes into labour and the hospital won't accept her???
