Bad attitude from customer care centre

I call Assupol Life on ********** 700 to request feedback if they received the requested documents to cancell my Education plan Policy AL ********** ********** 8, which i sent in on 1st of November 2017 for processing.On answering the call the consultant lady rudely told me it will take 21 working days to process the cancellation of the policy...I was so confused because she didnt even explain why it ll take 21 working days instead of 5 working days and there was no goodbye..call was dropped immediately while still asking..May i hear from the Assupol Finance department Superiors if thats how their consultants respond to Assupol valued clients..Thank you.
