Data Contract but no 3G signal

I signed up for a 10+10 gb data sim contract at Telkom mobile a couple of months back for R299 pm and i cant use the data at home because i dont have any 3G coverage. Now the best part of this whole issue is that when i app**** for the contract i asked the lady if i have 3G coverage where i live because i dont want to sign for anything that i cant use. After she checked on the system she said that i have full 3G coverage so it wont be a problem. I signed for the data contract sim card and was called a few days later to tell me that everything is fine and i can start using the sim card. to my surprise i couldnt connect to the telkom 3G signal via my router. i called telkom and they said that i must wait another day or two because it takes a few days. after no progress i took the sim and wifi router to a friends house and was able to use the sim card via the wifi router. i went back to the store where i signed for the contract and another lady there checked on the system and said that i dont have any 3G coverage where i live. she then told me that they will send out a technician. they have been here twice and im still waiting for answers. Im losing Data and money every month.
