All talk and no action - horrible service

Don from the DSTV installer company called Pinto talks too much but does very little. After the recent floods in KZN, our decoder continued with the error essage "no signal due to bad weather" so we contacted Don from Pinto, who came out, merely adjusted the LNB and charged us R550. A week and a half later the same message has come up and upon contacting Don he sends us numerous voice notes talking about how he only come through if we are replacing the LNB and how we need to pay him more in order to do this. We asked that he just come through and have a look at it again because he never mentioned that the LNB was a problem when he initially came through and charged us R550 and you ask for more money without even assessing it again is abit ridiculous. Then continued with voice notes talking about crediting us some portion but we will need to agree to pay more to replace the dish or LNB. It is absolutely to hold people hostage like this. DON was paid to do a service and obviously knew something was wrong with our dish and r LNB and would need repairs but instead of telling us that he just adjusted it , knowing that we need to call him again and he could get more money out of us. We asked for a refund for atleast a portion because he refuses to come out unless we agree to pay him more. He talks way to much and tries to manipulate people with his long drawn out voice notes. Please DO NOT USE PINTO DSTV INSTALLERS, Don is a very unreliable and shady character.
