I have had this problem with Airbnb several times past weeks. I had no access to my account on my App for many days. I contacted the Airbnb Support Team. The first person took me through a short procedure unstalling - installing which failed. She then referred me to another section and told me that they would contact me. Some hours later I received an email from the Security and Trust section. They informed me that they had detected unusual activity from another device and that they due to that had decided to lock my account. Of course I was never informed about this and had I not contacted them would never had known.
I was informed that my account was now unlocked but asked me to check that my telephone number was updated? It is the same number as it always has been. I was asked to verify my account again to prevent unusual activity from happening again. The Security team would guide me through the procedure.
But, when I contacted them again a new supporter from the first section had taken over my case. Without reading any previous correspondanse she went right back to scratch and asked me to take her through the whole procedure again. I just could not beleive it. All I wanted was for her to get back to the Security - Trust section and complete the verication. She refused.
She then insisterer that the problem was technical and advised me to use other devices. She blamed it all on my IPhone 6 plus. Even though I have been using the same device right up untill the lockout. She thought that mostly could have caught a BUG. My IPhone has newly been updated and I have had null problems with any of my others Apps.
After several emails back and forth I then told her I would contact the Supporter Team in my own country as their was little progress being made at her end.
The whole prosess has just been so frustrating and stressful.
it is important to have my App working and to secure my account from an Intruder.
