Discovery Bank shocking ineptitude

I changed to Discovery Bank to enjoy their seemingly good benefits and also because I make use of their other products Medical, Insure, Invest and Life. It has been a nightmare from the word go. Firstly I sent my new banking details to all concerned notifying them of my change in banking details. Other companies debited my new account as they used to do with my old account, the only company that could not manage to process the debit orders was Discovery themselves who could not figure out how to get money out of their own new bank account. They proceeded to suspend my Medical, Life and Investments for non payment and that only got resolved after 3 weeks of countless phone calls being transferred from one department to the next. Then I made the mistake and activated the iPhone benefit and it's been 3 weeks again of endless calling and transferring from Bank to Rewards and nobody seems to know how to fix my payback which is due as all the goals were achieved. Three different agents could not even tell me where the cashback gets paid to. For a company that has given me great service for the past 15 odd years this move to their bank has soured the whole relationship and I'm on the look out for service providers for all my Discovery products.
