INCOMPETENCE AND VOUCHER MISSING!

I did an upgrade October 2018, then on the 20th November I received e-mail from Samsung about the accessory voucher that came with the phone, I respond saying I never received any voucher, then Samsung gave me a contact number for further assistance, I contacted them, they ask me for the IMEI number and 'told me that there's R500 voucher that you were suppose to get when you purchased the phone , go to the store where you bought a phone'. Alright yesterday morning I went to Telkom Clearwater mall I told them Samsung story, the consultant told me I must go Samsung store to claim the voucher because his manager says there's no vouchers,luckily theres Samsung store in the mall, when I get to Samsung store they told me noo we need the proof of of purchase and a voucher. I had to go back to the same Telkom, then the different consultant assisted gave me proof of purchase and confirmed that yes on the system it shows yhat there's a R500 voucher, then I went to Samsung store only with proof of payment no voucher, consultant at Samsung store he sent me back to Telkom saying that they want an actual voucher, yhoooo like it was up and downs because of Incompent telkom staff. When I get there now for the 4th time, I told them Samsung store wants an actual voucher, what happened to the actual voucher? why wasnt I given the voucher on the day of purchase? The consultants changed the stories, the vouchers started in November, some phones came with vouchers some didn't, then I said how come Samsung sends me an email asking me about the voucher, also your system confirms that there's a voucher with IMEI, they couldn't answer. So what happens to customers vouchers??? It could only mean one thing 'THEFT'. Customers beware of the Telkom Clearwater Mall, they are ******, they ***** from customers and not to mention that they are so ***********. But I wont let this slide, I will get that voucher!
