Dissatisfied with Bonitas

Dissatisfied with the service from Bonitas Memberships maintenance department. After sending them documents such as ID copy, proof of bank account and 3rd party consent letter since 11 March they still keep on asking for the documents even though it has been sent to Bonitas multiple time by the broker and me, I spoke to an agent on Friday the 3rd of May via Bonitas WhatsApp, where the agent gave me his email address and I sent the documents to him as well and he confirmed he received it and the attachments opens when he clicks on it and that he will forward it to the relevant department but still they keep on asking for the documents!!!! How difficult could this really be??? I had to make a manual payment due to this incompetence!!!!
