Misinformation and the worst customer service

Good day,

I am very unsatisfied with your service. I received the attached text on the 1/10 stating that I will get R20 off my shop. I made 2 purchases and still did not get R20 off. I then called your call centre and a guy told me that he will escalate the matter and I will be contacted in 24 hours. A week went by and I was not contacted so I called again and the lady on the phone did not know anything!! I dont know how you employ people who doesn't know your product or promotions. She then logs this query again and after 10 mins of ending the call, I received the attached text stating only 1 voucher per month which does not make sense!! I feel missold amd misadvised! If this isnt resolved in the next 48 hours I will make a complaint on hellopeter so people are aware that you lie to customers. Not good for a bank thats starting up! Also I logged this complaint with tymebank on 29 oct and ive received no acknowledgement!!
