Standard bank not responding to my emails

I am staying abroad and I informed the bank before I leave South Africa,now I lost my bank and I received a new one,I cannot do nothing with a new card,I asked my Atm pin to be sent to my emails, because I do not use my SA number anymore. I did as instructed by the customer service,I sent an email with my details on the 3rd of March 2020. But I have not received any response from them. The country is currently on lockdown due to the Coronavirus,and I do not have money,I depend on my SA bank account.I cannot make international calls anymore.Can I please be contacted,or get a response through emails. I sent an email to *** And I sent to the branch in Mall of Africa ***
