Pathetic *********** service, unable to solve technical problems.

I have upgraded more than a week back and got a new device LG K61. From then I have been trying to install the FNB banking app on the device without any success. I just don't receive any OTP's. I have been uninstalling and installing the app numerous times. Been at FNB Swellendam more than 3 times. Trying to solve the problem through FNB's call centre. According to them the OTP'S is send by them, but its not delivered by Cell C. I have wasted countless hours and a lot of money. The lady Leandra at the Cell C Swellendam branch was really helpful. But the problem lies with the technical section. For more than a week I am unable to do my business online banking, unable to do payments. Image my frustration and losses.
