I bought a bicycle from Wal Mart in June this year. I've used it a few times, but today the chain completely wound up and I got it untangled, but it's not functioning. I'm thinking of returning it. I have the receipt, instruction manual, spare parts and everything. But I'm worried that they'll say it's been too long since I've bought it, or I've used it too much.
Long story short: Can I return this bike and get a full refund?
