Here's what happened:
I bought a Prepaid Koodo SIM card, and I went to the prepaid activation page. I filled out all the info, and chose to transfer my number from their parent TELUS. I got until the last page. When I clicked Finish or whatever that button said to complete the activation, it took a few minutes to reload, then I got some error that I don't remember.
I tried using the SIM card, but there was no service. So I thought it wasn't activated, and I tried to activate the same SIM card again but I couldn't because the website kept saying "Invalid SIM.” The email & password that I entered for Prepaid self-serve wasn't working either.
I had another Prepaid SIM card, so I activated that one, but this time I chose a random number from Koodo's available numbers. A few minutes after I activated that SIM card, I logged into Prepaid Self-Serve, and tried to transfer my number from TELUS, but I couldn’t because I kept getting an error that said We’re experiencing technical difficulties blah blah...
I waited a few days, and then tried again, but I kept getting the same error. So I decided to email Koodo. I sent an email to Koodo, explained everything, and asked them to do something about it. Two days later, I receive an email from TELUS saying "We're sorry to see you go." So I thought OK, Koodo CS transferred my number and activated the SIM card. NOPE. That SIM card is still not working. AND when I call my phone number, TELUS woman says the number is out-of-service now (yes, I’m calling from a different phone line ;)). I talked to TELUS, and they said the number was transferred out. My phone number is out-of-service for a few days now, and that prepaid SIM card is still not working.
I have a postpaid line and this number that Koodo lost is not that important, otherwise I’d have called TELUS and got it re-activated. Koodo customer service didn't fix the problem, but made it worse, and didn't even reply to my email. So thanks Koodo for your awesome customer service.
