I paid my monthly plan and an ad-on for international calls, but turned out i still got charged over 100 bucks for on air every month for three months. I went to the booth couple times and ask for help. All of them told me this was not a part of their job. One guy kindly gave me a number for costumer service but never worked. I have money in skype and wechat for international calls. If I knew it cost me for just answering international calls 1 dollar per min, I won't use koodo, I'll use skype. Until a collect agent called me gave me the right number, I tried to talk to koodo again, they told me it's out of their hand now. Told me I should pay them back and try call back again. I'm just a recent graduates with student loans to pay back, and I just got unemployed at this moment. 400 dollars is not a small amount. Would you please tell me if it's the best option to pay them back now and call back again? Or is it better I just wait for the ticket and take it to court. I chose koodo because it was suppose to be cheap. With less than half of year service I ended up paying 500 more phone bill.
