Lousy DSTV service from their staff

I was given rewards this month, but the Uber Eats voucher wouldn't work. Uber confirmed to me that the voucher had expired, despite it supposedly being valid until the 31st Jan. I spoke to Ntombi at DSTV. She said she'll escalate it. No response received by me from her. Then I spoke to Thulisili Mfeka 3 days later and she put me on hold and checked with the Rewards team. I was told that I would have my voucher by email within 15 minutes. No response. Nothing received. Today I phoned and spoke to a young man who told me there was nothing he could do to assist other than to email Thulisili and get her to contact me. I expressly told him to give me feedback today as to whats happening and he promised to phone me back with an update before he went home at 18h30. Nothing. No email or return call received. What a useless institution. I have been a customer for 30 years, and a Premium customer since DSTV began. They feel stuff all for us as customers!!!!!
