So dissapointed

Ive been with the service provide for over 10 years and have never been so dissapointed with them like i have been in the month of April and May.<br> <br> Last month I erroneously bought 2GB of data and was told that im unable to transfer data. I had no choice but to try and use up all the data, that meant me not haveing to switch off my connection at night. On the 20/05/2015 i forfieted close to 850MG. <br> <br> I then recharged my account with another Gig of data (20/05/2015). To my surprise the data was finished on the 21/05/2015 just before 15h00. How does that happen??? I then contact the helpdesk spoke to a gentleman by the name of Neo who was not at all sympathatic/empathatic to my query told me that the internet used up all my data and air time. This has never happened to me before, 30 MG can last a person 2days, but for 1 GB to last for not more than 48 hours is absurd.<br> <br> I'm a loyal customer and have never considered switching networks, with the way things are going one might as well as try the competitor.<br> <br> I'm very disspointed and angry at the level of service i recieved from the call centre.
