Personal loan worst service ever

Well I had lost my job and managed to get a settlement on my personal loan.. In April I called and they said that they will get back to me and I called again back in april then they told me they need a letter and I send them a email.. I'm the beginning of may I had allot of calles from various cell numbers and if you call back it will be engaged this how they contacted me by calling and drop the phone when I answer.. I them called back again and again and they managed to give me a settlement offer for 104k. This was in the 28th of may and they said I must pay before the 2nd of June.. They agreement amount was way more but I managed to sc***** what ever money I and my family had to pay before the Dude date.. I called again to confirm that the money was payed over and they said I must wait 10 working days.. It's already way past 10 day's.. Now on Monday I had 5 diffrent calles from the call center collections department asking me to pay more money.. When I asked about the agreement they check the system and just hang up on me.. I called again today and asked for my settlement letter.. Then they keep on transferring me to diffrent departments. No one wants to help me.
