Complains - Miway rewards

I am highly disappointed in the fact that I called in Miway early after I took out my policy advising them that I had issues with retrieving the miway rewards voucher, I was informed my query has been escalated back to the vouchers department to resend me the voucher & I should get a call from them within 3 days, after a week or 2 I decided to call the voucher department myself as I had not received any feedback from the Miway consultant. Upon speaking to the voucher department they advised me that since November 2018 their rights to resend the mail has been with drawn from them as a result Miway would be responsible to assist me directly, I then made another call to Miway last week for a consultant to tell me on the system my query has been sent to the voucher department so at this time I really felt I am being driven from pillar to post, I decided to have her Eva (Miway) and Nkosinathi (voucher dapertment) on the same call, Nathi confirmed once again Miway would be responsible to assist me, Eva quickly changed her statement saying no that should be the department (voucher) at Miway to assist me, I demanded that she give the line for that Miway department so I can have them join in on this call she then said I should together with Nathi she is going to speak to the "voucher department" at Miway, over 15-20minutes she returns to tell me they won't be able to assist me.
