Disappointing service

We had a very disappointing experience with Khaabo Tombstones, which there are not willing to resolve. We bought two tombstones and where long done paid for, when they were supposed to install, they flatly refused reasoning that the needed about six weeks prior to installation. Now we are asking for a refund and we told that we have to wait for a month. Basically we sent from pillar to post. their employee at Diepkloof square is not taking accountability for anything.
