*****ing data

Good day,I have been a customer of vodacom for the past 2months,ever since day 1 I have had problems with the data services provided by them,at first the package I chose assures me of 1gig data during the day and 1gig data at night,for the 1st 3minths they give you an additional 5gigs,which by my calculation is 6gigs of data.The first month I only recieved the additional 5gigs,half way through the month I had to phone in and enquire about my 1gig that originally came with the contract,I recieved it but "out of gesture" the following month I bought data because I ran out and just like that my data was taken from me,today the 27th at about 18:25 i bought again data and in an instant the data has been taken from me.I phone in and this woman has the audacity to tell me again that if they give me the data its out of Good gesture,please tell me how does 100megabytes disappear in 5minutes when all my apps are being restricted,I have got to the point where I do not want to pay my contract anymore,I am naming and shaming this company because I am extremely fed up,vodacoms data is so expensive and at the same time they are just taking my money just in an instant,I am here to warnpeople of this problem vodacom is giving me,I am not the only person that is experiencing this problem,I have been told that I have to wait 5days in order for some side of the company to figure out what the problem is!!!!this is an extremely bad company which gives disgusting services.
