FNB service lacking

Pathetic service. My account was flagged for transactions that paid money into my account which was *****ulent. Subsequently it was found the lady that reported it actually stole my band card and pin and gained access to my banking app and did the transactions herself to make it look like it was me. I reported to FNB and also opened a SAP case which is ongoing. I have sent all documents to FNB. They have put a reserved amount on my account for these transactions. I have contacted them on numerous occasions asking when it will be lifted, with the standard response they are escalating it and an advisor will contact me. This has now been goin on for over a month, with no response or contact. It is not the only problem I have with FNB. It is the most pathetic service I have ever received.
