Very unhappy with level of service & lack of help

Good day. This has been an ongoing issue and since getting hold of a consultant on your 111 line is near to impossible this seems like the next best thing. I have not had network connection at my house since I moved in in Oct 2015, due to your towers not being place in locations where their signal can overlap (please keep in mind that I live in suburbia and not in the middle of the Transkei so signal shouldn't be an issue). I was informed by the only helpful person on your staff, Jonathan, that a new tower is going to be build in my area, problem solved, by the end of the next financial year, AKA: June 2017. As this wont solve my immediate issue of paying for a service I don't receive, you were willing to give me 20% discount on the cheapest contract on my account, I have 2, for 6 months. This would also only be on my cellphone contract and not on my data contact, sorry for me. Now, I ask you with tears in my eyes....does this seem like a reasonable solution. NO!!! I have had time to think about this, and after receiving my invoice, sent after the promise of discount, and seeing there is no discount reflecting, I feel this is BS. I want to cancel my contracts, all of them!
