Disgusting service

<p>I had purchased tickets departing from jhb to London (Heathrow), 21st December of which was the worst flight ever. 1) The initial boarding gates where changed and No announcement's where made advising customers- The initial/original boarding gate was 10 mins away to the changed boarding gates for SAA236. The change of boarding gate was due to a smaller aircraft which was unacceptable. 2) the seats that we where allocated had NO multimedia (audio video)/ functional screens the entire 13 hour journey. <br />I have emailed and received a case reference ********** 76428 however no resolution was conducted as on our return back to SA on the 2 Jan 2017 we had pre- booked bulk head seats and paid a further R500 pp only to find out that my wifes seat audio video never worked the journey back.<br /> We are disgusted and disappointed that we had to endured such service. <br />We have brought this to the attention to a senior on the plane who was not very helpful.<br />Clearly SAA does not keep to the service level agreements& mission statement.</p> <p>I will be taking this up further to prevent others from enduring such discomfort on a long travel.</p> <p> </p>
