Dstv letting me down again

I initially had the hassle of getting installation done.I went to Dstv Umhlanga on the 30 March 2023,after continous requests for callbacks and assistance i laid a complaint on hellopeter and someone came out on the 8th April to install.Today is only the 18 April and the equipment is already giving me issues.Its a explora decoder and its giving me the following errors-Your decoder does not have a working hardrive and another message when you press ok their is also another line that states your hard drive may be *******.The decoder also makes a strange noise when turning it on.Now am i expected to take this decoder to get fixed which is only 10 days old,how will i be reimbursed.Why sell products or equipment that do not work.
