12 months and still signal problems

<p>12 months ago, I reported to Vodacom I am struggling with reception at my residence. It took them more than 3 months to come to my house to try and remedy the problem. This even after knowing the is a business line, with a monthly spend of R1000.00 on my mobile, besides my 3G connection. About 8 months later, they installed a cellfi unit and still reception is unacceptable. And I stay in Pinelands Cape Town, not Timbaktoo!!!!!!! Now a year later, still have the same problem, and told if I cancel the contracts, I will have to pay in excess of R10k! How do I address this, essentially I am paying for a service I am not receiving. VODACOM, PLEASE SEE THIS AND ASSIST ME!</p>
