Poor Customer Service and Lack of Communication

I initially app**** for assistance in 2016 and ended my service with the organisation in 2019 due to non-payment. Last month, I contacted your office to ask why I have still not been removed/cleared from the system. I received a response advising that my email had been forwarded to the Clearance Department for assistance. However, to date, I have received no further communication—not even an acknowledgement confirming receipt of my request. I am extremely frustrated by the lack of feedback, especially considering how long this matter has been outstanding.
