I have had a few issues with b and q over the years and this is just the latest in poor service, They are inflexible , the customer is always wrong and they always throw company policy at you, without trying to find a solution to the issue, A few months ago , I bought a small tin of paint, I placed it in my back pack and took it straight to my car. On getting home , the tin had opened and spilled all over my wallet and phone, luckily I managed to clean both without damage. The next day I went back to Greenwich store to replace the tin of paint, they refused saying it wasn't their responsibility that the tin opened and I would have to pay a further 25% of the cost if I wanted another tin. On the other hand I walked out of Homebase with a tin of paint which my toddler daughter knocked out of my hand, not only did they replace the tin of paint, they reassured me that they would clean up the mess which was clearly my fault, I am now a loyal Homebase customer. B and Q wouldn't exchange a tin of paint of the same brand , I just needed another colour without a receipt . I understand that I should have had a receipt but large companies also know when to compromise and b and Q are clueless about how to retain their customers loyalty
