Poor Service

My mom received a R75 off voucher on the 30th December through the post which expired the 24th Dec.Clearly this was not valid. she is a pensioner so I made the call on her behalf.I wasted 1 hour's worth of airtime on that call. Firsty being cut off all the time, then being put on hold by an agent named Sibongile Khumalo for 10 minutes to find concur,without coming back to me on the call.Then when I asked to speak to her supervisor she asked me 'why's that', with no telephone etiquette what so ever. 15 minutes later her supervisor, Sandile Mabaso then came to the phone and had the nerve to tell me the post was her choice to receive her correspondence. She's had this account for more than 30 yrs with no access to email and fax,so is that what is told to loyal clients.At 13h00 she eventually told me that she will get the voucher department to contact my mom within the next hour.Today is the 4th of Jan and to date nobody has contacted her.What appalling service this is. Must I spend another hour on the phone. The hour I spent is worth far more than the R75 voucher for which I clearly will not be compensated for.I am disgusted at the way clients are treated not to mention instore!!!!
