The customer service was amazing! They were very helpful and knowledgeable about all of their products. I didn't have any problems with them. I would highly recommend Dosh! The only thing I can think of is that they could maybe offer more frequent promotions. However, I do not believe this has ever been an issue for me. I am not sure if it's because I use my credit card so often or what but it's definitely worth trying out! I have never had a problem with Dosh. I love that I can earn points when I shop through them. I also love that they send me emails when there are new deals available. It helps keep me informed and keeps me motivated to continue using their services.
