********* Sales, and Don't care attitude

I took out a contract with Cell C and the package as promised was 1G but after some months I realised that my data were finishing out quickly and upon checking with Cell C was told that I have 500mb for a daytime and another for evening time. I disputed the explanation and they made me to hold while going on the recordings and only to find that indeed there was no mention of day and evening data split. I lodged this complaint on the 8/09/15 and to date Cell C is not even interested to give me a feedback other than worthless promises that my call has been escalated and someone will call me. Had I known that I was entering into ********* transaction surely I would have considered its competitors.
