The Foschini Group horrible treatment

I'm not one to always complain but this time I'm seriously disappointed with The Foschini Group after being so loyal to the company for so long.

All I wanted was to have my cell number changed from their system as I can't get the OTP on my new number because it has changed. I call and I'm being asked security questions which I answered according to what I know buy their system said I failed. I then said how unfair I feel the ways of verification processes is, the agent starts shouting at me telling me how she had told me I had to answer the questions correctly. Would I have answered the questions purposely wrong needing their assistance? I even provided my ID number which is mostly important. How am I able to even log on to my TFG account if I'm not the correct person? Now they tell me my card has been blocked.

Why was the agent not patient with me? I'm a paying client who never skipped payment but I'm being treated like a trash.

All I wanted was a change of a cell number so that I can be able to get the OTP number on the right cell. This happened just after I ordered online and did get the OTP but on the email which I want to get it on the cell number. Nothing complicated! !!!
