Consultant lying about Debit Order date.

This is so frustrating. First of all I requested a debit order date change through my broker never got feedback. Then I had to call you guys myself on the 24th of June 2015 after speaking to your consultant regards to my premium I asked the consultant more than once if my debit order has been changed he said yes it will go off on the 26th of June 2015 and then from July onwards it would be the 25th like requested. The debit order never went through and I had to phone you guys again just to be advised that my premium will only be deducted on the 30th of June 2015. THIS IS UNACCEPTABLE HOW CAN ONE PERSON SAY ONE THING AND THE OTHER SOMETHING ELSE??? If you guys lie about something like this what else can you lie about? And will I have the same service and lies when it comes to claiming? For a big company like yourselves I feel this is very unprofessional!
