unwanted debits and no services

Took a contract out with no permission what so ever to bill me for a couple of things like techtrace, hotspotter and other!try to send message on their own website and doesn't want to go through!I even try to call numerous times to try and resolve issues but the number doesn't work!There is debits that goes off my bank account every month now for over a year that I didn't want and just then it go off when there is no funds for these unwanted **** on my bank account, which leaves me with a bad name by my bank with 4 unpaid debit orders and my bank charge per unpaid debit order R138 and return item charge of R58 and the are 4 off these each month!I didn't want these things!Elite mobile is very bad when it comes to their customers!!!!I've tried to cancel the contract within 30 days when I took out the contract!now I'm stuck with bigger problems!My bank doesn't want to help me any more!!!The other thing is that I never ever had a invoice or what so ever from elite!!!they are just in for money with no caring about customer relations or service!!bad bad bad!!!
