Advertising in coverage, but not in coverage (Angry)

Not happy. My adress is listed in your coverage map and it clearly is not in coverage. I activated and paid R479 this afternoon, to my surprise 3hours later still not working. I have called several times to no help, only was told to set the APN correctly, it is set correctly it states NO NETWORK, I even emailed screen shots that its only MTN, vodacom and cellc and telkom thats listen if I do a manual network search. I drove a block away, and it worked there. I even did a speed test (2mbps). I also put the simcard in my phone, No network. Therefore I want it cancelled with immediate effect and my R479 refunded as I have no intrest in a product I cannot use at my house where it is intended to be used. You are more than welcome to come to my house and run your own tests as you will see there is no reception here. I know more than enough of network setups and how to set a APN up thats not the problem, its clear it works a block away and our house is not in coverage. Please cancel it immediately and process a refund back to my card I made a payment from and forward me this in writing via email confirming its canceled and refunded. Thank you
