On-Air Tv bad business

On-air tv promised to contact me within 7 days regarding the Explora that I don't want. Today they contacted me to ask about a debit order date when I was clear when I said that I do not want the Explora as it was sold to me under false pretense. I told them to collect the Explora because I cannot use it in my household, they assured me they will collect it and they have, that no fees are involved and that my contract will be cancelled. So today they called me about a debit order date for the Explora that they have collected.
