Pathetic service!

I've been trying to contact sanlam since the 01 Sept regarding the 2 pot system to change my contact details so I can apply for it online. Something as simple as changing a telephone number so I can access my benefits available to me. But the whatsapp number doesn't work it keeps sending the same options even though you choose a different option from the list, I tried choosing option 2 to change my number but it sends the option again. Then I tried calling twice first time I held on for an hour and a half so I had to drop because I ran out of airtime. Third time I held on for 20 minutes and had to drop because I had a meeting. Sent an email to that email address allocated for 2 pot no response, sent one to the SC email address they referred me to the same 2 pot email address and said they also referred it there. If this money is available for us to apply for then why are u making it so hard to get the money which is going to be heavily taxed anyways?? You can't tell me that the emails was not received by yourselves. And in future can you rather not have whatsapp lines if there's no one to test it for failures!
