Poor service from DSTV

I've received an email on the 12.02.2019 with a special on premium. on the 13.02.2019 i phoned in and the lady told me o sorry it was for Nov 2018 i told her but I've received yesterday - somebody will give you a call. On the 18.02.2019 still nobody phoned me, I've phoned in, the case has been escalating and someone will give me a call within the next 24 hour. Today, 19.02.2019 after 24 hours nobody phoned me (After the 24 hours), i phoned in and there is a 48 hours turnaround time. This case is far over 48 hours and still nobody phoned me and the call center cant put me through. Poor service
