Have had to apply twice

Hi app**** for the BA credit card as I travel a lot wih BA. I app**** 30 Oct, sent through all the relevant documents and signed acknowledgement letter, followed up and they hadn't recieved it- after literally holding on for at the very least 40 minutes at a time. I resent the documents around 5 times with the reference number in block brackets to no avail.<br> Eventually after 30 days my application expired and I had to do everything again. Which I did, and still they seem to not recieve my documents and no one ever phones back when they say they would. I have literally been on the phone holding for someone to answer for hours and hours the last few weeks. Your customer service is shocking! Do something about this.
