NO PROMO DATA 30GB NO FEEDBACK FROM MTN

Hi I would like to complain about the poor service from MTN , I renewed a contract on the 1st Oct 15 with a MTN LTE device ,in store I was not told of the promotion but later in the day I saw it on TV and on the net advertising the Promotional 30gb .I have contacted MTN 3 times now and been told once it has been escalated but I have never had feedback , told once to dial 808 when I had phoned them on 808 and finally after being told that I must go to the store I upgraded at that is 500km away the phone was dropped by the consultant when I told then I wanted to speak to a supervisor .<br> this is truly pathetic customer care Please can somebody contact me and give me some feedback<br> <br> thanks
