Ok in these circumstances you will be bound by the contract you signed and agreed to, which would make you liable to repay the money. If you missed the cancellation period then you can only really cancel with the company’s consent or if they have acted in breach of contract. Here it appears you changed your mind and decided the course was unsuitable for you, rather than the company breaching the contract, so if you wanted to cancel before the end you would be the one who is likely in breach of contract.
However, it does not mean you cannot cancel anyway and take the risk. What could happen is that you stop the payments and just advise them you are not continuing any further. However, they can consider pursuing you for what you still owe - they may not, but they can. If they did they could send debt collectors after you. They cannot do much apart from threaten you, and the only way the company can force you to pay them is to go to court and win. So this is the main risk - they may never actually go that far but if they did ten there is a potential that you may have to pay it anyway. SO there is no easy way out that guarantees you will not have any further liabilities but there are ways you can try and get away with it, not without its risks though.
The fact you are not using their services basically means that you may have to repay less than the full amount so that could help reduce the total liabilities.
