Poor system and *********** customer care

I have changed my debit order date from the 18 to the 25, the two consultants that I spoke to, they confirmed that my debit order is changed and I also received the debit check SMS. Today is the 15 but already m receiving the SMS that I am not covered because they haven't received payment, I fail to understand why they system shows the 15 for the debit date. Budget insurance stop being *********** and fix your system. My debit order is the 25 not the 15. Fix that mess NOW!
