Poor response

Hi responded the the FNB ad where FNB is now offering a cell phone Sim service. I have been a long standing client of FNB and thought the offer sounded good based on the internet and radio ad. I provided all my details, as requested on the website - on Friday 20 November, and FNB responded stating someone would contact me within 2 business days. When I had hear nothing by Thursday 26 November I again requested that someone contact me within the day. To date nobody has made contact with me. This is extremely frustrating and simply an unacceptable service. I have the email, dated 20 November that they would contact me within the stipulated period.
