No service from Sanlam

I went on pension the end of February and when I did my e-filing I had a directive for Sanlam. I tried for two months now to get a hold of someone to give me an IRP5 certificate. The phone number just keeps on ringing and the email says it doesn't exist. I tried another email, the automatic response is that someone will get back to me but nothing as yet. I now received a penalty from SARS due to the lack of any service from Sanlam.
