It would helpful if you mentioned who your LCO is. As you, yourself have stated that the problem is your lco whom excitel is using. At this point of time it's clear excitel in your area is unmanageable due to the LCO they are using, but in other areas excitel can be quite good as mentioned by others on the forum. You have done a great job in bringing about awareness, and doing a diligent, in depth review. It would be perfect if you could mentioned the root cause, the LCO so people can avoid the bad LCO irrespective of the ISP they subscribe to.
Well its true. My LCO told me that its more profitable for them to sell connections on their own rather than selling under Excitel. They provide same speeds for cheaper as Excitel pays them less money rather than a standalone consumer. That must be reason your LCO is not afraid on Excitel.
