FNB bad services to bussines banking

FNB put a hold on my accounts because one of my clients contacted them after a payment dispute and instead of contacting me they just put a hold on all my acounts even contacted Capitec to put a hold on, I flollowed all there procedures and resloved it with my client and brought rhem all the document in order to take hold off witch rhey did, but bow I have been phoning and pleading to get help to take hold of capitec as they gave instruction to put hold on capitec can not lift it without fnb contacting them. But no one in ***** department who is suposed to do this is answering there phones or emails or nothing. I have tried everything but no one wants to help
