Spam call from Multichoice

After my last review last month I complained about Multichoice spam calls I keep getting. I asked Multichoice not to give my number to 3rd parties to sell me things I do not want. As before Multichoice is either selling private numbers to 3rf party agents or some one in the department is doing that for them. I got another call to day from a 3rd Party and I said that I do not want to get any sales calls. If multichoice is so desperate to beg for clients the reduce the monthly dstv rates and they will then get more subscribers
