Bad Client Service

I wasn't working for 2 months and had fallen behind on my FINCHOICE account, so immediately after being back from work, I called and made arrangements and according to the consultant the arrangements where made, so got paid more than what I was expecting which led me in calling again and asking to still mainten my initial arrangements but just needed to pay extra as I had received more than what I normally get paid, that was a month ago fast forward to now, am being called 10 times or more, and I called and asked why am I receiving calls every day because I have horned my arrangements, I was passed around, so I was first transferred to Client Care then to Collections, then again to Customer Care, which I was advised they have placed a note on the system and I won't be getting any calls, well it just got worse instead of getting better couz today I was called 20+ times and some are dropping the calls and some are explaining the calling from FINCHOICE, my question is why am I called every day from 8 until 6PM 10+ and today more than 20+ times I have screen shorts, I even ask one of the consultant what do you need me to say, why am I being called if the arrangements are in place and honored what more do you want from me and she couldn't answer, please help me because now I feel am being harassed and don't know what to do or who to speak to, it's frustrating, even at work my manager is starting to complain about me being on my phone so many times and I can't even blocked them because they using different numbers and some are more like cell phone numbers and 021 numbers, I feel HARASSED and starting to regret taking out this companies loan🥹🥹🥹🥹🥹🥹
