SAMLAM REALITY THE WORSE

Just had the worse service ever from Snalam Reality. Trying to cancel the Sanlam reality programme and I am told there is a 30 days waiting period in which the debit order will still go through. My debit order goes in on the 15th and I had issued the notice on the 16th, and I am told by the consultant (Nonsikelelo) that they will still debit next month just for that 1 day. Is this fair practice?
