Pathetic service, no keeping of promises and theft

I was at the establishment with a group of friends and before we left we noticed the bill has been inflated and the waitress(Yvonne) was just plain rude, we complained about this and the manager promised to call me back. No call until today.

2. On Sunday morning after realising that I left my wi-fi router there I called, i spoke to Vanessa who promised to call back and she didn't. I called again after 3 hours, a message was taken for Vanessa and she still didn't return my call. Pity I can't remember the person who took my message, nonetheless I told her why i was calling.

3. Monday morning I called the establishment again and Nicky took the call looking for my wi-fi router, she promised to call back.

4. I called my data service provider who confirmed that the router is being in the vicinity of the establishment.

It is now Tuesday morning, I haven't received a call from these people not about the pathetic service we received on Saturday or the router that was ****** by one of their staff members.
