Poor customer service glitchy product

I signed up for LeadDelta because I heard they were the best CRM for business professionals using LinkedIn. I spent hours getting it set up and configured. I wanted to update my CRM contacts with the contact information from my Google account. So I went through the effort of migrating my Google contact data. But it created duplicates of all my contacts. I then tried to delete the duplicates, but the only option is to hide the imported contacts, there is no way to remove them. But hiding them does not remove them from the dashboard data. I reached out for help and had to argue with the customer support that my dashboard was indeed showing data for the hundreds of contacts I manually selected and hid. I was told they could not remove the contacts from their end. As a software engineer, I know it is not that hard to update a database. But I was told it was impossible. I politely asked for a refund, twice, but they refused, even though I had just subscribed 2 days prior and was never able to use the software to track my contacts. I had to contest the charges with the credit card company, and now LeadDelta is fighting the refund. I cannot believe their lack of customer service and care.
