UBER VOUCHERS ****

I quite had enough now...im done calling and begging for assistance. Vodacom logged a ticket for me on Sunday, i received an sms Wednesday to say its resolved and i should contact another company. This company only do deliveries....i took 8 uber vouchers on black frday, the 1st one worked the other 7 is not valid as per Uber, i called vodacom so many times, and i send another mail to the company they told me to sort it out with, i guess im also done threatning then now, I WILL REPORT THEM NOW for false advertising cause thats what it is, R 350 for 7 uber vouchers i cant do nothing with, i have the proof where i exchanged the vodabucks and all....im over this, all i got is automated responses...And i am sure this is all i will get now as well. The powerbanks i finally got sorted but the uber vouchers not yet. I am not sure which ref go with which query i will give both, but i need uber sorted please.
