In Ajax

I bought a groupon service for a simple eavestrough cleaning. This company did not do the work. After the technician left I went on my balcony only to see all of the eavestroughs in my view still filled with leaves. I don't know what this person did in 1/2 hr but he did not do the job I paid for. Instead he kept knocking on my door telling me about roof problems on a 3 yr old brand new house and offering to fix it for a cost that kept decreasing every time I said NO. Don't buy any group by deal from this company. I am so pissed off. I didn't bother to call them back to actually do the job. Thank god I only lost $40. I now have to hire a professional to get the job done.
