Here’s an anonymous tip for you.
My caller said her contract with Cashzone was due to finish in May. “I sent an email to give 12 months’ notice but I didn’t get an answer,” she said. “I re-sent and still got no answer. I called and left a message. Someone rang and said we got the email. They said I would get a call back but they also said I should have signed it.”
When I last spoke to her, they were still in correspondence and she wasn’t sure whether her cancellation had been accepted or not.
