Struggling to close account after card expired a year ago

I have been trying to close my Kulula account since last year Feb18 after my card was expired and have not used it for a very long time before that. Up until today (March 2019) I am still struggling to do that, no one returns my calls, I keep on being billed the monthly chrarges for a card I have destroyed long ago and which are expired and my emails to close the account are ignored. I feel like I am forced to pay for a service I do not want and certainly do not need.

I have decided to stop paying for these monthly fees and expect that I am refunded instead for all the fees paid since my card was out of use.

I know none of Kulula's management or whoever will respond to this as they have not done so to all of my other correspondence, but I would like to inform people to make an informed decision when applying for a card with them.
