Horrible service

I enrolled for the RE5 study support course and made a payment on the 29 September and was supposed to have received the study material 2 days later, I haven't received anything from them and when I try to call the landline it has been disconnected and emails are bouncing back, the CEO's cellphone number is also going straight to voicemail. The classes are supposed to start tomorrow the 6th. Can someone assist me.
