We had j&b come out on Friday 1-11-19 to fix a problem with our tank. On Saturday 1-12-19 we woke up with the same problem , we have called and left many messages . I'm sad to say they have not returned any of our calls and have not returned any of our 2,000 dollars. Now we are having to get up the money to pay another company , and are having to suffer and deal with this same problem until we can get the money up to have it fixed properly.If they would have returned some of our money , it would help with getting this problem fixed. I would advise anyone to chose someone else to do the job. read more
