Using your mts pre paid my account "Top up Account" link, I am unable to make ANY purchase. When I attempt to add credit card information, it wrongfully says "Invalid credit card information or system difficulty, please double check and try it agian". If choosing the "Interac Online" payment option, I get "Under Construction". I have NO way to make a payment and have no desire to go to a store and buy a new card every time that I want to make a payment! In this day and age, not having a working online payment system is ridiculous. When are you going to fix it or do I just need to go to another carrier actually that has a working system?
