Pathetic Service

Ever since I upgraded to a Samsung Galaxy S6 in May 2015 my GPRS keeps disconnecting despite my mobile data (MTN-SA) being active and being able to make and receive calls. I've had this issue since 16 May 2015 and have made several calls to Altech Autopage who reactivate my GPRS, however, this lasts for few days and the problem comes back. I even drove from Pretoria to the Midrand Headoffice on 4 June 2015 and was reassured that all was well but after a few days the same problem came back. Attempts to get through to the technical department since 22 June 2015 have proven futile as I keep getting disconnected whilst holding to go through. <br> <br> On 25 June I spent more than 45 minutes on the phone being passed from pillar to post, given a new task number: 739933 and told to disregard the previous one: ***.This does not help particularly if the problem persists and no one can reassure me that it is permanently solved! The technical department also cuts calls that are transferred! I wonder what is the point of having them if they cannot assist! <br> <br> This has been carrying on for too long. I have lost time and money trying to sort this! I need a permanent solution and I need it now
