Can you post some close ups of the chain?  It sounds like they have probably taken the depth gauges down too far.  In which case the only option is to re-sharpen the teeth and leave the depth gauges alone.  This time take it to someone who knows what they're doing.

You can see the depth gauge in this image, which controls how deep the main cutting teeth go into the wood.

Hi many thanks for your reply. See attached pictures, hopefully they tell you a story.  Cheers 

Thats absolutely horrendous.  Go and ask for your money back.

You'll be as well off just replacing the chain at this point i'm afraid.

Really, just robbed me £7. Ok nps ill do that, whats sharper a new chain or a 'properly' sharpened chain? And iam based cumbria id rather send it off somewhere to ensure l get a proper proffesional job! 

My dog could do a better job using his knob !

 A properly sharpened chain . A chain that is near the end of its useful working life , if sharpened properly,  will have narrower cutters thus removing less wood ( narrower kirfe )  therefore less resistance resulting in slightly faster cutting speed. I some times will give a new chain a stroke or two with a file if I have nothing better to do .   

I think a new chain would make sense, a quick google suggests they're about £7 on eBay.

Without wishing to sound harsh, I would suggest you would benefit from a little training if you didn't spot the chain was b*****ed after sharpening. A badly sharpened chain can cause more kickback as well as jamming.

I did a simple one day domestic course and learnt how to sharpen chains as well as basic maintenance and cutting.

Yea l know, sometimes you need something like this to give you a kick up the backside, ill look into courses etc. Ill go back in morning, is it better to use a better quality chain ie stil then a standard bog standard one? Cheers for comments and advice! 

You wont go wrong with Stihl chain, worth the extra

Thanks steve ill have a gander now 

Consider one of these sharpening kits.  They make it practically impossible to do it wrong.

Thanks mate, ill price them up now. Just bought this today  ye bye shitty macallister and it cosf the same as what l paid for macallister 

a better buy for sure

better new buy! and with a nice new chain. get the easy sharpening tool that Steve suggested if you're not sure what your doing but don't press down to hard when using it or the guide bars flex and you take to much off the depth gauges again.

Don't try to cut ground like the mute  mime artist guy in the vid.?
