Need my Lawnmower back!!!

So... I'd taken in my lawnmower for servicing and sharpening back on December 28th to Garden World (off Buck Owens Blvd.) where I bought it two years ago. Two years ago, I was pleased with the service and knowledge of the owner (who had been in the business for a LONG time) but since then he has retired and sold the company. I just figured it was still the place to take it for servicing as they still sell the same brand. The new guy told me that he was swamped with sharpening huge saw blades and wouldn't get to the mower for at least a week--I agreed to that. However, that was a total joke...several calls were made and he always had a "story" for why my mower wasn't done yet. I even went into the business hoping a face-to-face would put more urgency in my disgruntled customer complaints. Mind you, it has now been SIX weeks since I'd taken my lawn mower into this place!!! Had I been a gardener I'd've lost ALL my clients by now! Instead, I'm a simple homeowner dealing with 4 inch tall grass in my back yard and in desperate need of my mower back because it is NOT fun to pick dog poo out of grass that is tall and thick. Finally, in my desperation I took my weed-eater out back and just started scalping my lawn! About three hours later I had the whole yard whacked down nearly to the dirt and then began the tedious task of raking up all the carnage! After that I was so sore and even more irritated! Six and a half weeks since the drop off date, more phone calls and finally I was assured the mower would be done that Saturday after 3pm...Ha! By the time I settled the bill, (which was more than the original estimate) got the mower loaded it was AFTER 4:30!!! UGH...I do NOT recommend that anybody go there...I sure won't!!!
