Momentum Money Problem Not Resolved a Week Later

Cannot use Momentum Money, when I login, it tells me "We need to verify some more of your details for you to use Momentum Money. Please call us on ***so we can help you sort it out.". I have phoned the number multiple times since 1 December, but the query is still not sorted out, despite having received an sms saying I am now "FICA verified and can now enjoy an unlimited experience" on 5 December. I received one call back from Momentum Money (on 6 December) which did not resolve the query, and have not had any feedback since and still cannot use neither the app nor the website.
