Walter, we are more than happy to have you as a customer! We're glad to hear you are satisfied with our coverage and customer service. :)
You were quite helpful with the information regarding the repair to my Jeep. The repair shop commented he called and was told he would get a call back concerning the repair. He stated he called back to get the process and paperwork started. Thank you for your help! Sincerely, Dave

Dave, we're so glad to hear we could help you repair your Jeep! Thank YOU. :)
Very poor service! I recently purchased a vehicle along with a 3 year 40,000 mile warranty. The claim took over a week to process. There was mo communication with the dealer and at one point the adjuster cancelled the claim. Im not very happy and feel like this company is a scam! Thanks for taking my $2000!!

We bought a used car that came with a warranty from Diamond Warranty Corp. The vehicle required two major repairs during the warranty period. In both cases Diamond Warranty paid about 30% of the actual repair cost. Their maximum coverage limits are very low and you will experience significant out of pocket costs for repairs you expect to be covered under the warranty.

The service I got from Diamond Warranty was terrible. I have not had a car in 4 months. I made car payments and paid insurance but had no car to drive, not even a rental car. The automotive repair shop had called me after they started dealing with the company and said to come get the car, he didn't want to deal with them as they were pain in a$&!! You sell warranties but yet you don't want to pay for what is NEEDED. Once I can sell this car it is gone and I will NEVER buy used again. Diamond Warranty is not worth buying.

Price of part covered by warranty did not match the price the shop charged. Shops rate was higher than what the warranty covered. A $460 repair still cost me $230.

I had a claim under special circumstances that I was assured would be fully covered, but once it was processed, you failed to even cover the parts, much less the full coverage I was promised. Entirely misled.
