Long story short, phone broke so i didn't pay my bill due to not having my phone.
It has been about 5 months since I payed my last bill, so I am assuming they have closed my account.
My question is if they have closed my account can they open it again once I pay my outstanding balance???
Well that wasn't the responsible way to handle the phone being broken but that's besides the point.
By this time, you've likely done considerable harm to your credit. You can try to reapply for service after you pay your bill but Koodo will likely run another credit check. You're not likely to get credit from the same company again but Koodo is a little on the lenient side so might be worth a try.
If you run into problems like this in the future, call the provider and make arrangements.
