I joint c-date in Dec 2018. I chose 18.88 SGD member fee and c-date deducted 56.32 USD from my bank account. On 4th Feb 2019 c-date sent me an email to claim payment from me 206.88 SGD. If I don't pay these amount my case will hand over to debt collector. Anyone can tell me should pay these amount to c-date. If I don't agree to pay these amount will they court me?
