Very bad service

Very bad service at Nedbank I opened a business account with Nedbank in last year, covid 19 hit and we could do any business so Nedbank closed my account due to "no money in account" I then spoke to a lady who reopened my account for me, everything all good and well I made a payment into the account just to have money available in the account for monthly fees etc. On 19 Dec 2020 a client made a huge deposit into this account and on 24 Dec 2020 still no funds was showing also my mobile banking app showed R0 balance and no recent transactions even though I had made a payment into the account so I know there was money in the account, I phoned in to query this and to my surprise they told me that my account has been closed permanently from 16 November 2020 already without any one informing me, I still confirmed with Nedbank on 18 Dec 2020 that the account is open and I received and email stating the account is open but I find it very strange as I made a payment on 1 Dec 2020 and the money showed up in the account, I even purchased electricity on 16 Dec 2020 from the banking app so how can the account be closed? I am now battling to get answers, my client did a payment into my account but Nedbank said its impossible the money would bounce back to my clients account due to the fact that my account is closed. The money is still not reflecting back in my clients account as Nedbank stated it would bounce back immediately, I spend 2 hours in the bank on 05/01/21 to try and see what's going on, Nedbank say they don't have the money either in my "closed" account or Nedbanks suspense accounts, My client spoke to her bank ABSA and they say they are waiting on Nedbank to transfer the money back, no one can tell us where is the money! This is very frustrating and scary as this is a huge amount of money that no one can tell us where it is!!!!! I've spend hours on the phone with no luck! They payments went through successfully from my clients ABSA account, this confirmed by ABSA themselves, I have send the proof of payments to Nedbank and they still say no payments was received so basically the money just went missing. This is so embarrassing, I cant start the project for the client due to not having the money so every day I am loosing more and more money and more time to finish this project as my deadline is approaching very fast! Nedbank doesn't give a s*** about me loosing money especially in this difficult time period. I will never ever recommend Nedbank to anyone as your lack of service is shocking! I truly hope someone will get in contact with me ASAP to get this sorted.
