Account accidentally cancelled

I accidentally cancelled my account, and have incurred the charge for the remaining 4 months of my annual subscription (around £200).

However upon explaining my mistake to a chat rep, they told me the only thing I can do is start a new subscription, effectively meaning I have just lost £200 in the wind. They were very unhelpful in explaining anything or even answering the possibility of escalating this problem to someone higher up.

I consider this a relatively basic issue from a customer service point of view, it should be as simple as reactivating my account and carrying on as normal. I am not prepared to start another subsciption and throw away that money.

I hold my hands up to the initial mistake, In my line of work I am juggling a few accounts and wasn't paying attention to the fact my personal account was an annual sub, but it seems pretty bad that I can't find a phone number or get a straight answer form a chat rep.

If anyone has any ideas that would help, they would be most welcome.
