Very disappointed at the customer service levels

I've been on Neotel for a few months now, started off bumpy as installers left the property without actually checking if I was online properly, that problem fortunately was sorted out after a few days.<br> The problem I have now is I initially app**** for the 4mb line but was only approved for the 2mb line cause of affordability I'm assuming, in any case I took the 2mb line for 699.My frustration came along when not long after I'm seeing ads for the same 4mb line advertised for the same price I'm paying now which is 699. I take that as a huge slap in the face as that was the line I wanted and now its available for the price I'm paying. I've been trying to get someone to assist me with this query, which I believe is a small one, I've tried the call centre no one even tries and last week I sent an email to the complaints department and up to this day still no response. I'm very disappointed with the amount of effort I've received from Neotel in assisting me, all I'm asking for is to be moved up to the 4mb package as that is the one I initially wanted and it is for the same price I'm paying now so there's no discounts or anything involved. Simple customer service would've solved this.
