Bad Service and Dishonesty

I upgraded in Apr 2021. The consultant confirmed that my previous data contract would be cancelled and i would only be billed for my new contract. The past two months the data contract has been deducting once again from my account together with my upgrade. I now have to give them 30 days notice on something i never authorized in the first place. Regardless whether it is a small amount or not i feel that its very unprofessional and dishonest. This will definitely ensure that i think twice about using them once my contract is complete!!!!
