1. Identifying the problems, by getting in touch with customers, via emails, text messages, calls or face to face. While having the conversation, I'd have to pay attention and listen to them, in other to know what to work on. While listening to them, I'd show a body language of empathy while apologizing for the cause of the problem 

2. After identifying the problem with my team, i will brainstorm with them, by asking for everyone suggestions on how to gain back our customers, Would get a customers service expert to train my team and learn from others

3. Creating advertisements, giving discounts on every purchase and getting in touch with them in the best possible way

4. Discounts giving, a refund if there's any complaint 

5. A comment box, that would help us know how customers perceive our services, that way, we'd know what to work on and how to serve them better
