Garanti BBVA Contact Number Cannot Be Updated From Spain And Banking Access Is Blocked

I reside in Spain and I have been using the mobile phone number registered in your system, which was a Turkish GSM line, for my banking transactions. Due to a malfunction of my phone and my old SIM card being blocked and not working in my new device, I have lost all access to this number. Since my GSM operator does not send a new SIM card abroad, I now only use my Spanish mobile phone number. Despite having contacted your bank previously, my contact number unfortunately has not been changed. Your teams and the İzmit branch informed us that I would need to come to Turkey in person to change my phone number. However, I live in Spain, we have just had a baby, and it is not realistically possible for us to travel to Turkey solely to update a phone number. As BBVA is a Spanish bank and Garanti BBVA is part of this group, I find it even more incomprehensible that a customer living in Spain is left without any practical solution for such a basic process. Because my communication number has not been updated, I have been unable to carry out any banking transactions through internet and mobile banking for about one and a half months, which means I cannot access my accounts and cannot monitor any possible delays or balances in my Overdraft Account. We now do not know whether there is any delay on our overdraft, how much we need to pay or what our current debt situation is. I believe this responsibility should not be placed on us, but on Garanti BBVA, which has not offered a workable way to update my contact information from abroad. In order to resolve this situation and enable me to manage my accounts again, I kindly request that my former Turkish number registered in your system be removed and my new Spanish number and current e‑mail address be defined in your systems as my contact information. I also request that these updated contact details be used for all verification and notification processes so that I can securely access and manage all my banking services again. For privacy reasons I am not sharing my contact details publicly here, and I request that the bank contact me through the secure channels available to them to update my phone number and e‑mail address and to clearly inform me about the current status, delay (if any) and total debt of my Overdraft Account.
