Poor and slow service

Hello,<br> I have two mobile routers for my internet at home. One is on telkom mobile only and we have very poor coverage, the second one is on all network but when you select MTN is goes on data roaming - which I was not sure what it meant, until I woke up the next day and all my 5GB of data are gone. <br> <br> It's been two months since I have had multiple technical guys coming to my house to check and recheck that telkom has very poor coverage on our street in Brackenhurst. <br> I have multiple reference number and every time I have a tech guy or a consultant on the phone, promises are made but never go through. I was promised on Friday last week that the cancellation department will contact me on monday morning and that the person will follow up with me on Monday as well to ensure all went well. When I asked for a phone number in case nobody contacts me or I miss the call, then it is a no answer. <br> Well no call on Monday and on tuesday while in the shower someone with \no caller ID"contacted me. As I have no way of contacting them"
