VODACOM REWARDS BLUNDER

I tried to call Vodacom customer care after my 2 R50 Nandos vouchers had a problem. The store informed me my vouchers had expired on the 17 Jan 22 whereas the confirmation SMS from Vodacom had the 19th Jan 22. I tried to contact 135 to no avail. I then sent an email to *** all on 17 Jan 22(2 days before voucher expiry. On the 19th Jan I went to their @Vodacom111 customer care Twitter page and explained my situation only to be called on the 20 Jan and transferred to Vodacom Rewards. I spoke to an arrogant and reckless Sello who told me there is nothing they can do since the expiry date had passed without taking into account I communicated with the problem two days before expiry and they delayed from their side. The social media team has been keeping me hanging with empty promises and nothing happens. I wouldn't recommend anyone to use 135 which takes you on rollercoaster ride and email which is attended after a long time regardless of the urgency of the matter. I am so ****ed with Vodacom service.
