terrible service with staff that doesnt know what is going on or the processes

Totally disgusted

i logged a dispute as two accounts were prescribed, i have a letter from DMC stating that the last contact made to me was on the 8th of june 2020, therefore the 8th of june 2023 was 3 years and the account was to be prescribed. once the dispute was resolved only 1 DMC account was removed and the other still remained with an open status on my profile. i called in and spoke to an agent who then advised me that it needed to be closed and she will escalate it and it will be done in 2 days, a week passed and nothing happened. i didnt even receive and email or a call back. i then chatted to another agent on the live agent chat and she was so clueless, she said that dmc did not precribe my account and that they have a letter from dmc stating tis, i told her stay on the chat with me and email me this letter, the letter read...that the account is in fact prescribed, i asked her if she read it before sending it to me, she didnt not respond, she then spoke to a manager and came back to me to say exactly what the previous agent said, that she was going to escalate it to be removed and it will be done in 2 working days, its now another week that has passed and im wasting telephone calls and time trying to resolve this. i am totally and utterly disgusted
