TERRIBLE SERVICE FROM MONDO. STILL WAITING FOR MANAGER TO CALL ME AFTER 10 MONTHS STILL NO JOY.

I took out a modem package last November 2020 which includes vouchers R1500. I received the modem but no vouchers. I have tried calling Mondo numerous times over the past 10 months and no answer. I have emailed them also numerous times: *** and *** and it keep getting escalated. Now their email says the voucher was sent on 5 July. I still did not receive the vouchers. I requested the manager to physically pick up the phone and call me and still to date no call. Absolutely terrible service from Mondo. Please take your contracts out directly with MTN or the relevant provider but NOT WITH MONDO. Dishonest, ********* and pathetic service. Hopefully they can correct their mistakes and actually calling me and reimburse me for the promised vouchers. I dont understand why lie to the custoers? Why cheat them of the vouchers? How mny other people have they done this to? Why is Mtn affiliated with them?
