NO RESPONSE OR FEEDBACK FROM FNB!

Hi There , please assist , I have been doing multiple follow ups with regards to my credit limit increase , I initially requested a call back from the team on 7 March , of which a consultant contacted me , she assisted me with my application telephonically of which I then received a message to my banking app stating that the a debi check mandate was successfully updated?? I have not received any other update since , I have been following up since the week of the 7th , I then called on Saturday 12 March and I was advised that matter would be escalated , they advised that I should follow up by Monday 14th March after 12 of which I did. The consultant advised the matter was escalated , and I should follow up again on Tuesday the 15th AGAIN OF WHICH I DID! The I was told to follow up again on the 16th! AND NOW I HAVE HAD IT! How is it that with other financial institutes they were so quick to help my partner with his application this was STANDARD BANK - I WILL PUT IT OUT THERE! and he was sorted within 48hrs , me on the other hand thought I could trust my bank that I always found so "reputable" IS .OF.NO.ASSISTANCE! WHY??? Why does one have to struggle and continuously be redirected?? PLEASE GET BACK TO ME REGARDING THIS MATTER! As I honestly cannot waste my time anymore with follows ups and NO NO NO FEEDBACK BESIDE "WE HAVE ESCALATED"
