Has anyone else had this iPhone 5 problem?

I've had my iPhone 5 since November. Since then, I've been through around maybe 6 different charging cords. They'll work for a few weeks and then stop charging correctly. I've bought so many chargers I've probably paid more in chargers than I did for the actual phone. Should I call AT&T or apple or does anyone know any possible fixes?

Call them, it could also be you have been getting bad chargers, like ones that are fakes so they don't work well. I've had this problem before with my iPod touch 4th gen
