Terrible service experience

I left my previous employer on 31 May 2023. I submitted all the required documentation to transfer my full provident fund benefit to another provider.

It is now 13 July and the transfer is still not complete. When you call the call center they cannot even confirm whether documentation has been received, the administrators do not respond to emails from the other provider, etc. The other provider emailed them documentation on 4 July and still no response or feedback.

Each time there is some long, unreasonable turnaround time provided for feedback...... Can someone please just let me and the other provider know when the next steps (tax directive and payment to the new fund) will be completed?
