It's essential to get repeat customers, and unsatisfied customers are always fast to spread the word.

A few tips to stick to :

1. Be polite and act and sound professional – avoid familiarity.

2. The customer is always right. If it's a problem on his side, don’t tell him outright, give him the steps to fix it and be understanding. If the problem is on your side, do not be afraid to say sorry and explain the problem if the situation warrants it.

3. Offer a refund if the problem is serious. Tell the customers yourself that you will refund them if they wish, even if you have a clear guarantee displayed on your site.

4. Be willing to go the extra mile. It's the little things that count. When you can do more than asked do not be afraid to, your customers will love you for it.

5. Make your customer feel comfortable asking questions. Who knows, they could be planning a big purchase, or would have if they had been treated well.

6. Always follow-up if you expect a problem. It's always best to make sure everything is resolved before you move on. Make it easy to contact you if necessary.
