Bad Service from Neotel

I requested an upgrade from 2mbs to 4mbs. I received a call on Thursday the 31st of December that the upgrade had been successful and will take effect on the 1st of January 2016. However this is not the case. I have been calling Neotel call centre for the past 5 days without any resolution to the problem. No one seems to know what is happening. I was informed by of one of the Agents that the upgrade had been done but not provisioned on the System/network, and this has to be done by the NOC team, so it is beyond their control, all they can do is send an email. <br> <br> This is very poor service and speaking to a Manager is impossible. <br> <br> I am so frustrated by the poor service received from Neotel. The line is suppose to be 4Mbs, I am getting far less than 1.5Mbs
