Solar geyser installation pitfalls

Recently I spent a bit more than 14000 Rand on getting a solar geyser installed. It was a mission to get the money together. Some of that money came from my credit card. The geyser also included an Eskom rebate which was listed as a bit more than negative 4000 Rand, which then totaled in the 14000 amount. As far as I was concerned, the geyser was paid for at that company and installed and I just got to finish paying off my credit card as quickly as possible. I thought this Eskom rebate would be handled for me automatically.

Yesterday, I got an email about still owning over 4000. After some questions it turned out that I am supposed to pay that rebate amount as well and then take it up with Eskom to get the money back. If the original quote had said so from the beginning, then I could have planned my budget for it, now I got to make a plan on where to get that amount from. That company told me that they are so used to that, they they did not consider telling me about how this actually works. What me concerns, this is false quoting/advertising and misleading.

Note that the company that quoted for and installed the geyser was not Eskom. I did start to notice some saving on the pre-paid meter already.
