Perhaps wrong person to be asked to answer - my response will be
1. Definitely not a dishonest business
2. Hopefully not a awful manager/head - but my opinion doesnt count here one bit!

We are not perfect and I will be the first one to admit. And we know our flaws as well.
Considering we are part of a global setup there are elements of the business that we dont control - such as the product (website). And that does deliver a sub-optimal experience to our customers. In such events what we hope to do is to keep our customers as happy as we can - and thats why I spend a lot of time scanning the web for customer issues and resolving them.

You visibly havent had a bad experience and I checked that I havent heard from your side ever. Perhaps you have dropped in an email to our support and we havent been able to deliver on the promise.
Please write in to me on ankur.warikoo@groupon.com and I promise to make things happen.
