I upgraded my Unif line a few times from 5 to 10 then 20 then and finally they upgraded me to 50. All these done via Telephone so no of my equipment was replace. Last week I called to complain why I was not given new Router and new STB. I have to call a second time before they send their tech guy to replace my old Dlink DIR-615 with a TPLink Archer C1200 and the new HyppTV STB. No charges at all.

Well you can keep complaining that your internet speed is slow. The DIR-615 max WAN speed is 20MB.
So I ask TM tech support that I have to use my own equipment to connect to the internet, but when I call for support they say they do not support 3rd party product. So I ask how, like that the DIR-615 cannot run at good speed. What do you want to do, I refuse to close the case and call every alternate day. Tech support have KPI so if you call enough they will replace in the end.
