DMC debt management bullying me

Can I please have assistance with this company. They are calling me and harassing me telling me I owe them. They gave me an offer from Strauss Atterneys yo settle the account. After I hear DMC bought my debt and I explained to them that on the 31 March I settled the account with regards to Finchoice. They asked for the email with I sent to the their email:***. they said they never found my email and I asked please talk to Strauss where you bought the debt. This was end of March and they promised I will get my settlement letter between 14 and 30 days. When I called on the 15 April to ask for progress the rece0tion lady said it doesn't say that and when I read what the email says she said no it's just a saying ai will get my letter after 30 days and I must stop being rude so early in the morning when I asked why do they say that then on the emails because it is misleading. And she spoken in Zulu which I am NOT Zulu, I accommodated her with English and she screamed in Zulu.

It has been 60 Days. I HHAVE N9T RECEIVED MY SETTLEMENT LETTER. I am trying to pay off my debts but how does a single mother fight this when all calls I get a threatening mebinstead of helping me settle this account. They say nothing is on their system and may I ask, whose fault is that, mine as a client, receptionist who is rude or DMC for not having their things in order. I am tirednof this, can I please get assistance from anyone willing to help adn then they are going to come back and say they are listing me for defaulting the account. And ITC will just list it without even c9nfirming anything with me. PLEASE HELP ME. I am so tired of bully attorneys.
