No response from Capitec Bank regarding inaccessible account

Reading the reviews here is getting really worried because I am being given the same non-response treatment regarding the query I lodged weeks ago. I am abroad with no access to my SA number/simcard and have found that it is now required to "activate" the new app on my phone. I tried calling the customer care number I'm kept on hold indefinitely. I sent emails and all I receive is an autoresponse that they will get back to me in 2 working days; its been weeks now and I still can't access my account, my kids are suffering! Could you guys at Capitec Bank please have empathy???
