Terrible and slow service from business accounts

We have recently moved a stokvel account From Standard bank and moved it to FNB due to terrible service. Only to find that when we move the account to FNB the service is just as bad. This account was opened on the 6th of January and till to this day there is issues with the account. The business area which handles these accounts is the business accounts team but I am not happy with their service. I keep on receiving emails requesting FICA documents when I have supp**** them with everything. The account number in question is called the Improvement Investment Club. Could someone please sort this issue out and have this account in order, else we will be forced to move our business elsewhere
