Contract cancelled but still been billed

Good day

I am utterly disgusted by the service I have received from Yellodata. I have called the call centre countless time requesting that my contract be cancelled and in all the calls I have made the consultant confirms that my contract has been cancelled.

But guess what, my account is still been debited (over a year now). The one time the consultant told me that Yello data will always find a way to debit your account even if you requested for cancellation of the contract.

I wouldnt advise a dead man to take up a contract with Yello data.....
