HORRIBLE SERVICE FROM MOMENTUM MYRIAD!!!!!!!!!

I have been a Momentum Myriad Policy holder for over 2yrs now, paying quite a bit per month. I've recently changed bank details which I clearly communicated this to them via email and got confirmation of the change, however its the 4th and I have not been debited, so I called to find out whats happening, to my shock I am told my policy has lapsed, and the last successful debit was May, NO COMMUNICATION OF SUCH WAS GIVEN, no email, no sms nothing!!! I guess after having paid so much over the past 2 yrs monthly works to their advantage, they got free cash with no claim and I have lost all of that money. By the way when I called to find this out I was transferred to Lapsed accounts department, I held for over 30mins only to be dropped. Called again, while speaking with an agent to put me through again, i was dropped again. When they want your business its all roses and sweetness, once they have you, THEIR AFTER SALES SERVICE IS HORRIBLE!!!!! Had i died, my family would not be covered. How sad is that!!!! TERRIBLE SERVICE!
