FNB app and Customer Services MASSIVE FAILURE

App**** on the FNB app @ the "shop products" for a galaxy s22 ultra... got approved but when trying to finalize it shows an error.. I have been trying to contact FNB regarding this.. and they have been "looking into the error". I have been calling daily. No one has even tried reaching out to me to get this sorted.. This is really not a service I should expect from FNB. I moved over to FNB for a reason.... Can ANYONE please call me or mail me.
