Irate policy holder

I sent a cancellation letter and wanted a acknowledgement by close of business today (9 Feb) from Chandre Judas... NO RESPONSE. If i see that money is deducted from my bank account at the end of the month, there will be trouble. I expect a response from Senior Management regarding this matter and NOT a call centre clerk by close of business tomorrow (10 Feb). If i do not get the requested response - i will be taking this further!
