Poor signal and Poor service

<p>I have been in contact with DST since last week but do not have resolution to my problem. In April last year, I opted for the Explora Price-Lock deal. I used a DSTV-accredited technician for the installation. I started to experience signal issues with the first week. The installer advised that I needed to replace the LNB. This did not make sense as it was new. The signal improved somewhat and I ignored this matter not wanting to incur an additional cost. More than a year later, the signal issues have become progressively worse, to the extent that I only receive a handful of channels in the evening. 2 weeks ago I contacted a different DSTV accredited installer who explained that DSTV would have replaced the LNB free of charge within the first 12 months of the contract as they had issues with the LNB's. At no point did DSTV or their installer advise me that I need to swop the LNB free of charge. I now expect that this will be resolved at no aqdditional cost to me. After 4 calls I did receive a call yesterday, but this was from their sales department wanting to offer me a Price-lock deal. REALLY??</p>
