YOU ARE THAT IMPOSSIBLE SCAMMERS

YOU ARE THAT IMPOSSIBLE SCAMMERS
I switched 2 months ago because I thought yes these suppliers will be able to do their job, so far I have been allowed to call and send emails because you cannot look at your own site?
I fill in an advance invoice, I suddenly get a bill from the DOUBLE ???? This is unheard of, worst suppliers ever
NOT RECOMMENDED AT ANYONE! BAD CUSTOMER SERVICE and simply DON'T listen to the questions !!!!!
