FURIOUS!!! UNAUTHORISED DEBITS FROM A DODGY INSTITUTION WHO AVOIDS ANSWERING THEIR PHONES

There is absolutely no customer service, I've been on hold for over an hour and keep getting told my call is first in line but no one answers, they keep pushing you you to let them call you back. The messaging service from their website also doesnt work. I've tried on 2 separate numbers with no avail. There are 3 unknown unauthorised debits coming off my account which I have no knowledge of and unfortunately my bank was no no help either - how are people allowed to just debit your account without your permission?!?!?! AFTER WAITING FOR OVER AN HOUR SOME ANSWERED AND THEN HUNG UP ON ME
