Very poor network coverage

I have been struggling with proper network coverage since I received a router from you,but this problem has gone from bad to worse beginning Thursday the 20th July .I am very disappointed in the product, it was a Mistake for me to move from rain in the name of a free to use ups …My initial thought was that maybe it’s a speed problem in the first month,I then upgraded to a faster speed but that did nothing, you can’t have more speed if the unit does not work to begin with. I’ve called in to have to problem addressed and the response I got was “We need to troubleshoot, tors this can only be done when you are done and connected to the unit @i work 7 days a week at times ,only get home after 7 on weekends…Now tell me when am I supposed “Trouble shoot “over the phone. I know what you are going to tell me, when you bought the product you were informed that connectivity was not guaranteed,I get that but I’m not paying for something that doesn’t work,I can’t be restarting it 10-20 times a day ,I need a solution,I need it to work it’s either you move me from Mtn to telkom which is the only other network you have I believe or OUTLINED FOR ME HOW I CAN GET OUT OF THIS ARRANGEMENT, in its current state I won’t be your customer by the end of August.
