Unable to get through to consultants

I am experiencing problems when contacting your call centre from the beginning of the year, on the voice prompts I do not get an option to press a number to be put through to an agent. I called in from a different phone and it works well, I tried several numbers and all is good but mine has a problem. I spoke to this other agent who said it normally does that when your call centre is congested with calls, I was calling from a different phone, but the question is... why is it congested when I only call from my phone? It doesn't matter what time I call , and bear in mind that I am using my own airtime.<br> <br> PLEASE delink my number from your systems so it wouldn't recognise who is calling. <br> <br> This below is what it gives me when I call.<br> <br> \ Your service is active
