COMPLETELY IGNORED MY REPEATED REQUESTS. In mid November 2016 I made a Subject Access Request (SAR) to Vodafone under the Data Protection Act. I did this after appalling service from their bad service dept. The law requires the information I requested to be given within 40m days although the Information Commissioner's Office (ICO) suggests that a reasonable response time is 21 days. Vodafone ignored me for 90 days then found my request and are 27 days into their  legal time. UNREASONABLE!!!! This company make a practice of making life as difficult as possible for customers who complain or who need assistance. If you are in that position I urge you to make a (SAR) . It may cost £10. They make this payment as difficult as possible by insisting it is paid by cheque (who uses cheques these days?). You will be told that they only accept SAR's requests online. This is rubbish! The law says that you can make the request by letter or by phone if you want. I suggest that you make the request by registered mail and insist that they contact you only by snail mail. This will cause them great inconvenience and expense, just as they do to their customers. Ask for transcripts of all telephone conversations and chat rooms. After my 10th weekly letter I advised them I was making a charge for correspondence to or from them. I should have made this charge after the 2nd letter. When this affair if completed I will invoice them and, if necessary I will take them to the small claims Court. Good Luck all. I will keep this site (and others) posted on my progress.  Good Luck and Regards, Frank M
