Disfunctional Wi Fi

My wi fi hasn't been working for the past 2 month. The matter was reported to Telkom on a number of occasions but no help was provided since they only sent a technician ones to come and have a look at it, but the problem was not solved. I have run out of strength and patience with Telkom because they know that they are the only company that provides land line service to the country and they take people for a ride because of that
