Computech, biggest **********!

I keep on getting calls from this company and texts threatening to send a judgement against me at first I thought it was just misinformation I called them and enquired about this money I am said to owe them,they said it must have been someone who was using my email address to which they asked me to get an affidavit, I was rubbed off by this but after calling and explaining that how much this was needed I went and got it. I have never heard of this company until I received these notifications,I even asked them to show me proof of what I owe and they couldn't so I sent them the affidavit as asked, after a couple of months the calls started again, I had to explain the same story even via email. Finally some lady said I had asked Computech to find a loan service provider for me and this is what I need to pay for,at this stage I was curious and told them not to ever call me again,since this was complete madness...I thought someone must have used my email address as they said at first now I realised they just a company partaking in ***** and they go around de*****ing people. Until this day they cannot show me proof of whatever I owe yet they keep on sending texts and emails. This company is for **********! This even needed to be printed to the Ombudsman to question this institution or whatever it is! I am just so sick of it!
