Discovery Bank: The future of banking that resorts to toll free communication only only

I really and wholeheartedly would like to understand something.

If I take a look at the majority of major banks in South Africa, Each Bank will have multiple departments, say for example: Bank A: Bank A has a Credit Department. Bank A's credit department has an email address. Bank A has a email address for any general queries for their clients. My point is that I notice almost all major banks in South Africa, their sub divisons etc, don't only have telephonic numbers, but also EMAIL ADRESSES. I work overseas on a ship, where there is zero cellular signal, and I most certainly will not pay to receive a call from Discovery Bank when I get precious time offs****. I am just going through Discovery Bank's contact details: To summarise, Discovery Bank only makes available a toll free number within South African borders, for absolutely anything. Because I am not a, 'impaired hearing' client - according to Discovery Bank I cannot use, ' ***' - and lastly to submit a complaint, I have to circle back to dialling a number which is simply impossible for me.

Discovery Bank claims to be the future of banking (now) offering all sorts of fancy features and banking products, yet cannot provide me as a client who works abroad onboard a cruise liner, with a simple solution (such as an email addres) to contact the bank whilst overseas. 'We'll call again'' ? Why? If when Discovery has called 5000 times, and all 5000 times have not been answered.

Honestly just unphased as Discovery Bank has, in my opinion, simply gone downhill.
