Vodacom Shake is a *****

Vodacom Shake is all a ****, in August 2020 I brought a watch voucher via the app but as soon as I logged into the Edgars online store I was told the code was invalid, I did queries and was sent from pillar to post and was made to forget it. In January 2021 I received a Netflorist discount voucher of R100, I was told the voucher only works on PC, and I did that but it still said "invalid" until it expired. Mid February 2021 I received a voucher for Uber of an amount of R100 and also that voucher was "invalid", I sent numerous emails, tweets, Tobi queries, etc but was sent from pillar to post, all vouchers and coupons expired and Vodacom just said "they never assist me as they also don't understand the system", so now we are made to recharge, use Vodabucks for nothing as we are being ****** and if they can't really assist one, they must rather return those Vodabucks or as this is their responsibility the whole shake competition, we need to be reimbursed.
