Stay away from Blue Label Connect

I cancelled my contract.Paid the amount that was said I must pay.The phone broke within an year HTC Wildfire.Now they say I must still pay over 3000 and they can't pick up anywhere to whom I spoke and that I cancelled the contract.Even the banks says we need to stay away from Blue Label Connect.Can't even buy airtime or data like with other cell service providers and banks. THEY ARE ****MERS.
