Absa blocking my account while out of the country

I am in Mozambique for the December holiday. My Absa banking app on my phone was blocked. I can still go onto internet banking on my laptop, but can not do any transactions, as my verifications get sent to my phones app. I called the Absa helpline and they said I need to go to a branch to get a security code. I told them that I am over 700 km from the nearest branch. They then said I need to send a request via email and ask for a downgrade, that the verifications get sent to my email, then I would be able to payments again. After several calls and emails I only get acknoweldgements of my emails and reference numbers. It’s now been 4 days (90+ hours) and the consultants said it takes anything between 24 to 48 hours. Still noting! I need to pay my staff, VAT, ect. Absa, it seems client service is not on your priority list! I’ve been with Absa for close to 30 years. Is it time for a change? Pierre Griffioen
