Ahhh Just up my alley this thread. I moan and complain at any slight fault and usually get away with it with gifts etc.
Moaned at a 2 for 1 pub because on the menu the Sunday roast had boiled potatoes, no one told us otherwise, and all 6 of us wanted them obviously lol! got a free round of drinks.
Around our estate the council is replacing all the gas/eleccy /boilers and a few months ago they came on the install day to do ours. They turned up at 8:00am, 5 mins looking around then went in their van and drove off. I instantly phoned up the Head of Customer Services( Mitie the company was), moaned and moaned. Their excuse was the guys thought it would take more than the one alloted day and needed to reschedual. No date was conveniant. Anyway long story short - blagged a second brand new Fireplace for our front room, which they dont replace. Result!
To be fair, when it comes to meals if it isnt 100% perfect, when they come to ask me was it ok, i will moan, usually get half price or just pay for one meal something like that.
HSBC - Im sure a few of you have done this the old claiming back your charges. I got a, get lost letter, then got the address of one of the head honchos and moaned at him. Promptly within 2 days all charges refunded. Wicked!
Mr Kipling - moaned that a box of French Fancies had one missing. Sent me a £2 pound voucher.... Morrisons had a 3 for £2 offer at the time - Result!
The local Tesco - Heinz Spaghetti and Sausage tins. Year or two ago when it just opened. The shelf ticket said 74p, quite cheap took 12. Went through till came up at 78p! Outrage! Went to customer services moaned etc. Apparently their policy was, if they charged us more than the shelf ticket said they would refund what you paid and the same again for the inconvenience AND still get the product. Crackin result there.
Ive had loads more successes, but too much to get on this shortlist. The secret is if its not 100% satisfactory, then MOAN its your right. However dont ever raise voices, swear or use personal insults. They get you nowhere.
In the past 2-3 years I dont think ive lost a complaint, and ive done a few! Always get refunded and more often than not i get something on top "good will gestures".
