Why my automatic refill is never working?

I have been trying to get my pre-paid service on automatic refill for past 3 months. However, each month I have to phone the customer services to manually refill it with my credit card. The last 2 phone calls happened in past 2 days, first one I was told that automatic refill will be on the next day. Second time I phoned, I was told that there was no record of automatic refill or registration of the automatic refill although the history showed that I have requested the service back in May. I was given excuses after excuses by the rep. Following is the list of excuses given to me:
1. I was told to wait for 5 more days to make the automatic refill to be done.
2. When I questioned that automatic refill should be acting every 30 days and should be working right away, I was informed that there was a technical problem and I am not along.
3. When I told him that my phone has been inactivated for 5 days and I would like to solve the problem over the phone, he said I have to activate the phone by filling the phone first.
4. I finally gave up and provide him my credit card (again) to refill the phone, then I was informed that my credit card number does not match my account so I have to check with my bank to make sure my credit card is ok.
After this I was really fad up and decided that there is no way I can get help from this rep. So I asked him if I can just purchase the voucher and refill the phone. The rep reply that I can only do that when the phone is activated and I need to have my credit card checked first. At that moment I felt that I was like a dog chasing its own tail....I am going no where.
I am considering changing a plan to other cell phone provider and I have to say that although he left a cheerful farewell message on saying 'I appreciate your patience and thank you for choosing Fido.'; I would really think what he meant is 'Thank you for giving up on trying and never call back again.'. If you want, I have written down the name of the rep and the time that I made this phone call.
