CRACKED TOMBSTONE

I bought 2 tombstones from Forget me Not and hardly a year, the one tombstone has cracked. I am now informed that the cracked tombstone had been cracked due to the supposedly earth tremor that had happened. I am amazed as the other tombstone had not been touched by the earth tremor. To date, I have been informed that a manager will assist me, but I am still at a loss. I have read a comment herein where somebody mentioned that Forget Me Not has a approximate 22 year guarantee on their tombstone, I wonder if that guarantee is selective as it does not apply to me. I am greatly disappointed. My family and I intend unveiling these tombstones in September and I am sure it will be embarrassing for us to unveil a cracked tombstone. That is what we call value for money!!!
