Need to deregister Sure Signal on expired business account

[burgundy]

We need to deregister the device which was previously registered to my husband's old business account. The Sure Signal hasn't been used for some time and got overlooked. Can you help please.  PS. I am still with Vodafone and was/possibly still am a "user" on the Sure Signal unit. Ta.
