Poor service

RAM got the details wrong on their delivery slip, so I could not take delivery, this was 3 weeks ago. I arranged for the purchase to be redelivered and they made exactly the same mistake again, despite the fact that the supplier had double checked with them to make sure it did not happen again. Guess what, they repeated the mistake. So by this time I have spent a total of 5 working days waiting for something I still did not get. I phoned to discuss this with their management, the call agent promised to connect me and nothing happened. Disgusting.
