Just 4 u

So i sent a message through the app enquiring for this Just 4 u data....FACT my offers has been the same since the past 4 months.As far as i understand these are chnged from time to time calculated over by your spent but mine it has changed nor even varied I check it everyday more than 10 times a day but no change hence i thought let me send a technical enquiry maybe mine is not refreshing So a gentlemen which i did not get his name ....i will give you the number he used to caĺl me it looks like Christopher according to true caller was so rude and self absorbed He did not listen to a word i say but insisted on calling me a **** because his Just 4 u data refreshes and chnges from time to time so therefore i must be lying This kind of behaviour is not acceptable for customer serving personnel....firstly he was not listening to a word i was saying because he was right i was wrong and he even went on and raised his voice when i told him that what he is saying is not what im experiencing on MY DEVICE but he was barking and sarcastic at the same time Please i dont have a problem porting back to MTN if when i raise a concern im being bu**** into be told that im.lying If these offers cannot change he could just say so because the offer i get that i can use is wau too expensive for me weekly(10G for R159 ) for past four months If this cannot be resolved please let us know so we can find networks we can afford which i believe was a tone of the agent when he spoke to me
