I cannot recommend this company's customer service highly enough. I am a small private customer, not a big business or anything. I made a mistake with the drilling of the hole in my tank, and the Tank shop could have easily fobbed me off as a 'nobody', but they went out of their way and persisted with the manufacturer to provide me with plastic plates of the right thickness to help cover and seal the holes. Being able to talk with a human being who takes responsibility to help if they can when things go wrong, instead of making a submission through an online form is becoming rarer and rarer. Providing they don't change the way they deal with customers, this company deserve support over their competitors because of a humanity that is all too rare in business nowadays.
