Does telkom not want my business?

I ordered an Lte home network system online and was told that I would be contacted within 48 hours. It is now a week later... Noone has called to confirm my order. I want to find another supplier instead, but during the online process they ask for your banking details. I don't want to sign up with another company just to have Telkom start billing me for a service I've not wanted because of bad sales service.
