Ethical business Strand Electro Bug

I had to fix a faulty element on my geyser. I got hold of a plumbing contractor using an App but it turned out to be very expensive. I then contacted Electra Bug, Strand. They quote me R700 cheaper on labour and I opted to use their service. They came the same day and installed the new element. Due to a break in communication I was also charged form a thermostat. The issue was raised with the owner who immediately said that they will rectify the matter and I was refunded in full. I can only take my hat off and say thank you for your professional service and the way in which you resolved the misunderstanding.
