However its 2 days later and the squeal is back as bad as ever and its driving me nuts!
Has anyone any suggestions?

Answers:
Most in Likely when they replaced your brakes they used a metallic or even a ceramic pad, take it back to the garage and have another tech look at it ( not the one that did the job) he could be new and is trying to do everything by the book, tell the new tech to rough up the new pads surface usually accomplished by taking the new pad an rubbing them in a circular motion on the concrete just enough to rough up the surface, re - install and your noise will go away, This may sound dtrange but If you notice most shops will not allow you in the garage while your repairs are being done, This is the reason why if the general public ever saw how repair work was actually done they would have a hissy, There are only two ways to do mechanic work, By The Book , Or the way that works, Good Luck
Could be they didn't clean the old dust out of them properly
yes
get them to chamfer the pads with a rasp just the edges works every time.
The squeal is caused by the pads vibrating in the caliper. This is normally always cured by copper slicking the new pads on all surfaces that come into contact with the calliper which sounds like it has not been done properly. Another reason could be a sticking piston inside the caliper but highly unlikely due to the age of the car. Hope this helps
Had the same problem with mine ! I changed the disc`s as there was a little lip on the inside edge of them and the pad`s were`nt sitting properly , i also opted for genuine pad`s as the cheapo ones the garage used still made a noise with the new disc`s aswell ! you can also buy anti squeal shim`s that stick onto the back of the pad`s ( instead of using copper slip ) copper slip only last`s for a few weeks then you have to do it all over again! good luck ..
Seems sorted by the above answers. Make sure you are firm with the garage that this is their problem , and you will not back down until it is fixed to your satisfaction.
cheap brake material is the only thing that squeals
take it back and demand a refund or genuine brakes.
genuine pads for a start - make sure the discs are not too badly lipped - if they are replace them if not chamfer the edges of the pads - and also did they look at the rear? if they are drums they will need to stripped down and the shoes sanded down the top and bottom edges especially - then cleaned down.
