Nedbank does not respond to emails/applications after being told process is simple

I have attempted on more than 3 occasions to have 3 months payment relief app**** to my loan and credit card account however im still receiving smses from nedbank advising that i should ensure that funds are available. Since the 25th i have been receiving notifications that debits are being requested but there are no funds. I have emailed nedbank 4 times and completed the online form for the loan account and credit card. This is really bad service as I've even attempted calling in, the call is dropped. I am also unable to cancel the debit order with my bank as i need to contact nedbank to do so. Would really appreciate feedback as soon as possible as ive been waiting for weeks now
