Discovery Bank - A shocker of note

I have been banking with Discovery since the bank opened. I have always kept my credit record intact and have always prepaid my credit card in advance. Recently Nedbank changed their website and from which I had always made payment. Discovery is listed on their website as a defined beneficiary and was used for purposes of making payment. A few days later I called Discovery as I saw the payment did not reflect. This was followed by 6 emails and a further 5 telephone calls to resolve this matter but which was never done. Apparently the deposit was found in a FNB suspense account and they just could not attend to the transfer between banks for some reason which seems to be sheer incompetence. The calls made also require verification by way of a pin which is forwarded by sms but which you never receive in time and which then requires a manual verification which is extremely frustrating. Out of sheer frustration I then sent email no 7 threatening to cancel the card and viola it was done in an instant and without even a call. My suggestion after having this shocking experience is that they should rather opt out of the banking sector and rather focus on their core business and it seems that their service levels are non existent or their staff are ***********
