FNB not the same anymore, no will to assist its clients

Not happy with FNB's response to my hellopeter complaint. I signed up for a R479 data provision with Rain and they (Rain) suddenly stopped providing the data, but continued to debit my account even though I had cancelled the 'agreement' with them - they just continued used debiting my account. I asked FNB to stop the debit orders but they (FNB) bluntly refused and said I must cancel with the service provider (Rain). So stupid - the reason I asked them (FNB) was because Rain did not stop debiting my account even after I have cancelled the agreement with them (on their failure to provide data I've been paying for). Now I'm forced to close my account with FNB for failing to assist me with this.
