Totally disappointed Poor Service

In Sep 2023 i was contacted by an agent from the company and i was advised that they can assist me. I advised the agent of my situation and i was guaranteed that they can help me .In Dec i get a call advising me that all was in order. I Jan i get told that they are still awaiting docs from another company, and nothing has been finalized. Please not that within this time i have made payments to them. I have been sending emails whatsapp messages calls and to date i have not gotten any feedback from them and this is after they have taken my money and promised me that my issue will be resolved.
