Fraud payment help, pls

This is terrible, this is fraud.
that I did not use the account.
This company has tried several times to write off payments. I did not configure the tariff. Then they sent a letter that they themselves changed the tariff and somehow began to write off payments!
I can write support in it. Nowhere is there a telephone or email.
Please tell me what to do?
