POOR SERVICE NO RESPONSE TO EMAILS

On the 19th April I called customer service to complain about the Makro Voucher which is declining in store. I sent an email to DSTVhelp and to Lesego . Lesego never replies to emails, I did get a response from DSTV Rewards on the 23/04 requesting all my info and the voucher info. to date no feedback no responses to my emails, with the previous complaint I was told I will receive an email regarding my free upgrade, still waiting for that email. Highly annoyed with yours service.
