before christmas, i have bought something oversea, and 2 months later i have received a letter from controlaccount said i have to pay a outstanding fee of £108.16 on their website. I have searched controlaccount plc on google and found a lot bad reputation of it says it is a scam. I am a foreign student and this is the first time I encounter something like this. Should i pay them or is it really a scam that i should ignore?
