Fail to respond and deliver service

I have app**** for partial annuity on the 8th May. I bought a small business and needed the money urgently. At the local branch the 2persons who was suppose to follow up the application are either off sick or make promises to call me back which never happened. So I went to the client service department. The guy phoned and promised to follow up what is the problem. So he also fail to give me feedback why the money is not paid in yet. I submitted all the info which the wanted even if its several times. I again phoned this department and he promised to phone back which he failed. It is now almost a month since application.I am so upset with this kind of service and its not even their money!. I had many negative financial implications due to their delay and to deliver a proper service. I had to use my personal allowance for the shop not to loose everything I have already invested in it. I am also willing to name and shame them
