Irritated Customer!

I started a new job at 121 10th Rd, Kew, Johannesburg where there is hardly any Telkom Mobile signal(but says full signal according to your website.) On my first day of work, I phoned 180 and was advised to turn my data roaming on to connect to my out of bundle data. My 150mg of finished about a week and a half before the end of the month. I phoned 180 again on Monday morning 2 February 2015, where I was transferred to DATA. I spoke to a lady by the name of Yvonne who was not helpful at all - after being on hold for most of 20 minutes - she advised that she would phone me back after she had opened the case which to this minute - she HAS NOT phoned back. So I decided to call back and request to speak to her this morning and someone from Customer Care put me in the \queue"for 24minutes! When I tried calling 180 twice again after that"
