Lack of customer care

1. It is a no-frills warehouse (Greenstone), so don't expect personal service. 2. Right from the start of using the office chair I bought, I had trouble - it kept on lowering - it did not keep the height at which I set it. 3. I rang (the only number is a central one). It took at least 25 minutes to get to talk to someone only to be told that I had to send the shop where I bought it an email. 4. Email quoting Order No, Item No etc sent outlining the problem. 5. One week on, not response. 6. Another 30 minutes on the phone. The person who answered tried to put me through to the store manager without success. I left my number for the manager to ring me back. 7. the day has gone by and nobody has rung me.
