LACK OF SERVICE

I have a faulty smart TV, i laid a support call in April the 30th, i had a technician come out only to tell me he didn't bring a replacement TV to match my spec and will be back the following day. Dominic the support agent call me 1 week later confining my TV is a known dud (not sure why teljoy sells dud tvs) and will be sent for replacement from Hiesens. that was 3 weeks ago, on Monday the 14th i was informed that a technician will call me to come collect the TV and give a replacement, im still waiting. this service is ridiculous. im paying for a TV that doesn't work and the lack of service and client contact is dismal. im tired of following up with teljoy and doing there job.
