I know that we all have had experience of different types of after sales but today I have had 3 distinct experiences in after sales service.

Type one was from a firm called Black Diamond they make after market brake parts for cars, I had a set of front discs from then a while back, I thought it was in the last 12 months but it turned out to be over 16 months ago.

The problem was build up of rust on the disc and even thought the brakes were older than 12 months as a goodwill gesture they have replaced them free of charge.

Second experience today was from a firm called Parcel2go, I'd tried to send a parcel a few weeks ago and waited all day and nobody turned up, so they "gave" me a £5 credit towards my next parcel.

I've only used them twice in 3 years but on this occasion I tried to use them again today, went through all the site until it came to pay, that's when I found out that you can only use the £5 credit if you have more in the pre-payment than the cost of the delivery.

So the charge is £5.85 but to use the £5 credit towards the £5.85 you have to put in £20 credit, the best part is the £20 is non refundable.

Third experience from a Sheffield firm called Sheffield Windows who came out and replaced a sealed unit that had blown after it being in place for 13 years.

Because he had not remembered to give me a price before changing the unit it came free of charge, his reasoning was that he should have quoted before replacing so the firm would stand to the charge.

So two firms both with completely different ideas about how to treat customers and one firm who thinks you are there for their convenience.

So a big thumbs up for Black Diamond and thank you to Sheffield Windows.
