Worst service ever

I contacted Express treadmill services because I had a problem with my treadmill and needed it repaired.They sent out a technician to my home and I had to pay an initial assessment fee of R500 which I did on completion of his assessment.The technician found out that there was a problem with the Main control board and had to be taken back to his workshop for further testing to analyse if the board could be repaired or alternatively be replaced. I was sent through an email stating that the Board had to be replaced which I agreed to at a price of R3220.00 inclusive of vat.The technician fitted the so called new board and the treadmill worked fine for +-4 hrs and then had the exact same fault.He came out to me and found that the new board that he fitted needed an upgrade because of a problem with the motor .He then took it back to this workshop and I got a call a week later stating that they were going to fit a 2nd hand motor at their cos***** been over a month now that they have been promising to come and sort it out,making appointments and not turning up.They also don't answer your calls as they have your number stored on there cellphones and landlines.Please do not do business with this company as they will take your money and you will never see them again .I have never come across another company that is so *********** and unprofessional .They also don't have a business address on their invoice so probably working out of a garage in a residential home .I am now taking this matter further and handing them over for collection .They should also change their name as they are definitely not "EXPRESS"
