This is the worst company I have ever dealt with

I am beyond angry, upsetting and disappointed in this company, I signed up with DebtBusters in dec 2019, debit orders went off my account as usual every month and I have never had any questions or queries.. however when I finally decided to query on certain stuff I would usually get feedback after a week or so, I thought nothing of it since I never had any interaction before regarding queries while being under debt review, however it would go on whenever I need to find out something someone will call me back in two weeks time asking if I received help??? Two weeks later?.. nonetheless I recently settled 3 of my outstanding accounts and asked debtbusters not to pay those accounts come the 25th and rather refunded the money into my account, again, I received feedback after a week or so from a guy named Tyrone that I would be refunded within 12 calendar days from the 25th July, fine I don’t have a problem.. 12 days pass by still nothing, on the 5th of August I follow up on my request, this time round I’m speaking to someone else and the guy tells me that Tyrone will get back to me, he escalated with the payments department, I will get paid out on Monday 8th august, still nothing, I follow up again and this time round I copy a few people in the email, I eventually ended up sending a message to debtbusters on Facebook and that’s how I got a response because the campaign team escalated it, the story then changes and I get told that I will be refunded after 12 days, fine, it’s almost 20mins that has gone by, I emailed the retentions manager, I received no feedback, I sent a mail on the email address provided on the system, usually I’ll get a email back saying my query will be attended to, nothing, somehow I got the CEO’s email and emailed him hoping that there would be some sort of urgency or pressure, nothing again, everytime I call there’s no answer, I’m usually holding for more than 15mins and then I end the call, this morning I tried again and still nothing.. honestly is this the type of company that I need to be dealing with, I come from a customer service environment and I know what’s it like to ensure that your client is satisfied, I feel like I have been treated with the utmost disrespect in this regard, I refuse to move forward with this company and I need to be refunded to me what’s due to me urgently I refuse to wait a day longer.
