Pathetic service

I am very upset with the service I have received from discovery vitality. I registered my pregnancy in November and received a 10% discount off selected products at Toys r us. I then went today and purchased a pram of which I had to get R250 off , when I gave them the code it said invalid token. I then called the call centre and they couldnt assist immediately . I waited on the line for more than 30 minutes and I was at the store for nearly 2 hours and I was on a lunch break. I explained to the manager Pindile that this store is far from where I stay and work. I took the time today just to come purchase the pram in order to get that off my tick list . I was on the line for more than 30 minutes, they dropped the call and didnt even have the decency to call back.
