Poor customer relations

I am a client at NDC and have been struggling since the 02nd of March 2021 for my funds to be refunded to me. Senusha assisted me as my allocated consultant with NO success. I was then passed to Jedele who senior whom does not respond to emails . I have to constantly call her for feedback . Her attitude towards me as a client is poor when I question when will the refund happen as Senusha mention within 7 working days from the 03rd of March and Jedele herself stated itwould have the refund 26th March 2021 and I have not to date. Jedele speaks over me and her tone is of frustration . Up until today I have not received my refund. My account is fully paid up and paid up letters have been submitted. They have even proceeded to close my profile by issuing me with a clearance certificate with incorrect details but failed to refund my cash and informed I get it myself. Disgusting service and its a business that does not provide a professional service but care for themselves as an organization.
