No compassion or ethics

I must say I am so disappointed in the service i have received form Impaq homes schooling. My husband wanted to enroll our child with Impaq in 2017 (this is now 4 years ago) but was forced to cancel the application relating to his work situation and the fact that the person who would have given the home schooling (his ex wife) left and he could not home school the child himself this making it impossible to home school at that stage. At the end of last year we decided to look into home school again as we think this is the best option for our son and we got someone who will be able to home school him full time sorting out the issue of us both working full day. I registered him under my own name (he is my step son) and had issues with the system not taking his ID number. I called the next day and was helped and said that the system picks up his ID from the 2017 application and it was corrected and sorted out. I paid the FULL year's study fees in one payment and was now happy to know that it was sorted and that his year is covered. We logged into the portal yesterday to check if the portal is active as he wants to fami****ize himself with he system in the meantime. I had to see an outstanding amount on the account. I called and enquired about this as the FULL year is paid for and there should not be a "PAY NOW" amount on my account. The person who assisted me tried to explain that it was overdue monies written off from 2017 and now put on my account but he said he is not trained to give me the information i needed i must sent an email. I did. The response was .... unbelievable. I was told that there was in 2017 a cancellation fee that was not paid (my husband was aware of no such outstanding amount as he cancelled) and now it was load on MY account. I told them that i did not even register him that time. How could they even hold me responsible for this? The answer is simple, i have to pay. "sorry for the inconvenience caused" was said. But i have to pay. Firstly i think it stinks that this is over 4 years ago and secondly i was not even the one who registered him that time. I am no FORCED to pay the account this is not even mine and that my husband was not even aware of!!! I told them that this was written off apparently so i request them to write off as i have paid in full for this year. They just said no, i need to pay it. I am unhappy and i feel it was a bad way to handle this. When i had many conversations with them last year to fix the application to accept his ID, i was never once told of an outstanding amount for him.
