Dissatisfied customer

I have paid up all my accounts in July 2024, i have send the paid upletters to 4 different people working at MSD consulting and stil after 3 and a half months have not received my clearance certificate. Each month that i make an enquiry i need new paid up letters, even if the banks send it directly to the company. Then they want a paid up letter on an account that was paid 2 years ago, but they were quick to take their fee each month, but not quick yo render the service that youpay for aka clearing your name.
