Unathorised debit and no contact details

I have been debittes without my authorisation and cannot get a hold of payjustnow. The bot is useless and there is no number to contact this company.

I have sent several emails but no reply.

They *****ing our money and the dont reply. It is pathetic that payjustnow can do this to people.
