Attend to my matter!!

Zero customer service or communication. I have been waiting a week for a request approval. I have been given a contact number for Kabelo whom is apparently in charge of my matter.. 13 days now and not once does that number ring. Always busy. Morning, afternoon and late afternoon. I logged a complaint and was told a manager would contact me. This did not happen. Everyday I sit without a vehicle as the negligence continues from MFC Finance Department. My Brand is battling to get someone to attend to emails. Please can MFC do something..
