CIPAV returning 2019 pension contributions

As reported on here a while ago CIPAV are offering to return your 2019 pension contributions without reducing you pension entitlement.

Unlike the other refunds from the impots etc. doing this requires persistence,

They will eventualliy respond but they refer you to an external website that they use for financial transactions.

It is very sloppy internet security protocal but CIPAV using seems to be entirely legitimate.

CIPAV will send you a non-secure email with a link to a web address.

Seems legit but what does anybody else think?
