Policy Amended but Miway still debits

I got new insurance. My broker sent a letter of me cancelling the insurance and miway didn't do it, even though the email was read. So they debited. I reversed the debit order as i was debited by both insurances. I phoned in and cancelled the policy. After a week it was still active as the debit order was loaded again after the reversal. I was penalized by the bank because there was no funds. I called in and demanded to speak to a senior consultant/manager as the previous manager was very rude and didn't want hear my side of it. The consultant then told me to rather amend the policy and just keep the accident and death cover which is R9.90 on my Profile to assist me to not pay the initiation fee if i was ever to return to miway. I did this and an updated schedule was mailed to me. Yesterday another debit went off. AFTER making 3 call back request over the course of 2 and a half weeks no one form miway could or wanted to assist. For a company that prides themselves for good customer feedback and service. This is very poor. I wouldn't recommend miway to my enemy and they always tell me how poor other insurances are, while they themselves are the benchmark.
