Pathetic service from Vodacom

I purchased pick n pay vouchers @R9 +60VB x5 which should be R45 and 300VB on the 07/04/2022 then I received 1 Voucher instead of 5 the worse part, you can't call the call Centre if you do it throws you to a robot where you must always be on the phone typing, to top it all they deducted 60VB again, I have been chatting with them via my wife's Twitter account and they keep asking me the same questions, asking me to send screens hots whereas they can see on their system what the hell is going on, the worse part I bought it because I needed certain things in the house and they have been taking me for a ride, I'm tired, my cell no is *** and the most annoying thing is that you can't contact then when you have an issue, so it's either you get tired and forget about your money or you keep begging them via social media which is time consuming, I seriously need a service provider who will value me as a customer not a company that gives me the middle finger when they should deliver
