Disappointing

My husband bought me a Moto G 2nd generation 4G. Its a lovely device. I was so excited to have it and the service we got before the phone arrived was good. However, a month after using the phone the speakers on the phone just stopped working. I could only use the phone with headphones to answer. We decided to send the phone back. We had to pay for a courier to take the phone back. A day after sending the phone back we got an email to say they received the phone and would proceed with the repairs on the speakers. That was on the 7th of July. Its now been more than 30 days and there has been no update or anything. Unless we send an email asking them what's happening, they don't say anything. And the answer is when the repair centre responds we will update you. I think I've been very patient but I'm really getting frustrated now. I always worried about shopping online because II feared that if there was ever a problem with the product you wouldn't be protected and Orange is feeding into that fear. Its been more than a month without a phone and the company doesn't seem to be concerned at all.
