angry and disappointed

I'm so disappointed with dstv multichoice, they have called me, informing me of price-lock explore deal, I was sold and took their offer. later on I received an sms informing me of installing the device on the 31st Oct 2022, i took a day off from work, but they didn't come, didn't say anything at all. what bothers me now is the fact that I am still receiving calls about this deal...I am so angry and disappointed honestly and is not like dstv is the best and stuff, they can cancel my request because I wont take leave again for such reason
