Discovery Bank - Absolute Frustration

I am totally frustrated with Discovery Bank and their inability to resolve my issue for months now. I have tried to order a new credit card as the one I had was lost. I have been unable to do so as my Discovery App continues to say migration in process. I have spent hours talking to different call centre agents, met with a Discovery Bank consultant, had call backs which eventually dissipate into nothing as not one person can help me to date. Yet we have continued to pay our monthly premiums without the benefit of using our credit card. We had decided last month to stop paying our premium as not one Discovery Bank agent has managed to help us to date but the minute our account is in arrears we get a phone call to ask when it will be paid up. Two months of interest charge at R1,000 a pop. I now want to cancel my credit card and can't do that either because yet again the app. does not allow me to do so. Both my husband and I are completely frustrated, the hours and phone bills wasted on this over a period of approximately 6 months, if anything we should get re-reimbursed but we are getting charged interested instead. Right now a home affairs department are giving Discovery Bank a run for their money.
