Pathetic service and account blocked

Most pathetic service ever received from Capitec Business. In September 2023 I received documents to complete with regards to FICA requirements on my business account which I did and returned it back to the relevant person who send the documents. Yesterday, after several of my transactions declined at shops, I contacted the bank just to confirm that my account was blocked because I did not send back my documents. I've been battling since yesterday afternoon up till now after 12:30 to get my account unblocked as my husband is stranded in a different town and can not get home because he can not fill up his vehicle to travel!!! This is very pathetic from your side as all the documents was submitted in September. Can a competent manager who can attend to my problem and urgency of this matter please make contact with me.
