Blake & Associates vulgar language unacceptable

I made a payment arrangement with a consultant, every month a different consultant will call for payment however a consultant named Darshan called me who was very rude all I said to him, i am busy now please send me ur bank details I will make payment now, I told him twice and his reply to me is "oh you always very busy", then I got ****ed cos his repeating what he said "oh you always busy" even though twice I told him I'm busy send me your bank details and I will make payment now, so I swore him and he told me "**** you too" and cut the call, so I called the office and requested the call recording, then management tried to cover up this matter as they sent me a call recording that was cut off before the guy swore me and management is trying to cover up this matter insisting that the call recording that was sent to me is the only one they have but they sent me an apology letter indicating the consultant using vulgar language on me, I have the money to pay my account in full however I will not pay anything further until I receive the full recording or contacted by the directors, this is unacceptable and I don't want this to happen to anyone else going forward, blake & associates need to employ qualified agents not just anyone with no knowledge of how to speak to clients, I will continue to red flag this company until this matter is resolved.
