bad service from dstv

On the 21st Jan i took up the offer of DSTV explora, this was a terrible decision on my part , considering the drama that followed. I received the package on the 24th Jan and on the 26th contacted the accredited installers on the dstv website. The vast majority were not in the Lenasia area which i stay in which is bizarre. I got hold of Ntate installers and they agreed to come that afternoon. During the "installation" they were unable to complete as it was more complicated than anticipated, but promised to return on monday or tuesday to finish the job. However after they left half the channels did not work error e 48 no signal . Even worse the people in the flat also now have the same issue even though they on a communal dish and i have a stand alone dish. I asked Ntate to come thru to fix and he said he would come on Monday 28 Jan and than promised tuesday 29 Jan but he never arrived eventually not even taking my calls. I sms'd him to rather leave the installation as i would ask DSTV to send another installer. I phoned multichoice and explained the situation that day 29 Jan and they promised to get back to me within 48 hours . No feedback received since. Also an unrelated issue DSTV charged me R400 extra on my last debit order and was assured they would refund in 10 days this was on the 21 Jan , still no refund. The service from DSTV multichoice is disgusting, i have no explora connected , i am paying for a service that doesnt work and my neighbours also have this problem with no resolution in sight
