Bad Service from DSTV

I am the PA to a couple who own several holiday homes. I need to be able to switch these DSTV's on and off as needed. This weekend the website did not work, I called DSTV and they simply refused to help me even though I had all the information they needed... I was not the owner. On top of this, I discovered that the DSTV was on in another one of their holiday houses, but we requested DSTV to put it off on the 10th of September. But they would not switch it off. DSTV should be assisting people more - they need the business, but if this keeps going on we will be cancelling all our DSTVs contracts. Please can a manager call me to sort this issue out, and to refund us on a DSTV decoder that was not switched off when requested. Thanks, Shelley
