I've had this problem ever since I switched to koodo over two years ago, and it still has not been resolved.
When I login, it works, I have my wifes number as well as my own on one account. I can view her usage, rate plan, and order new phones/change plans no problem...but not on my number. When I click on my number, it just says "oops, something went wrong". When I ordered a new phone over a year ago, I had to use her number and then switch the sim cards. Right now, I am wanting to take advantage of the summer sale and upgrade my plan, but cannot do so. I have called support 3 times, they have told me it should be fixed within 24 hours and that they would call me to confirm, neither of these things happen. I am about at the end of my rope and will be switching carriers soon if I can't get this fixed.
I have scheduled another call tomorrow to ask why they didn't call back and why it still isn't fixed. ( I have tried clearing cash, cookies, used other browsers/networks/devices, nothing changes).
