Pathetic Service and Technical Support

I have purchased an Open View HD Decoder on Sunday 19th July and I arrived home to set it up. Everything worked perfectly with no hassles at first once I activated the Set Up Box. The next day I switched it on and the signal strength is 96% and the quality is on 100% but yet not channels seem to be working not even the promo channel 100. I have since then made numerous calls to the customer care line, but this line keeps ringing no one has ever answered, 5 minutes ago was my 15th call for the day. They advertise all the time on etv telling customers to buy their product and once the customer buys it, they do not care. They should atleast have a 24hour call centre for these issues just as how Dstv has theres. I have never experienced poor service at this before. It is really disgusting and I will not recommend this service offered by etv to anyone, rather be safe and stick with your dstv or top tv. This is disgraceful, really shocked that etv would lie to the customers and sell such a pathetic product.
