I also have been getting calls from 513-333-4357 ... not frequently ... but enough times to bug the [***] out of me. I told them I already have a yearly maintenance contract with another local company; and that I do NOT want to get calls from them again. But, I just received a call from them again today which I did not answer. I know times are tough ... but I just don't care for this sort of phone hassles.
Used Thompson once to clear a sewer line. I think I gave them my home and cell #. It's been a couple of years at least and they are always calling both numbers. They also told me I had a broken sewage line which another company said was not true. No wonder they have such a low BBB rating!
