DATA DISAPPEARING ON TELKOM MOBILE WIFI!!!!

i am on the R99,00 5G mobile Wifi package with Telkom. From 2 Jan 2018, my data has been disappearing within the first 5 days of being loaded. This was strange is i was in an area that does not have telkom coverage and therefore had to buy mobile data to roam on the MTN network! I was told that on 02 Jan, i used 3G of data and the balance was used on the 5th or so. Again in Feb 2018, the same thing happened and again this month on 09 March the same thing. I called in last month to request assistance with changing my password incase my card was hacked which i did and checked how many devices were connected and it showed 1. I have been waiting countless times for the different Managers to call me to no avail. the last consultant i spoke with was regarding this matter was Tarryn Bronwyn Oliphant as i wanted to escalate this issue coz i cannot be paying for services i am not receiving and telkom is not willing to come to the party to resolve this. Their pathetic absent customer service is appalling to say the least and when i inquired about cancelling the contract i was told i would have to pay over R1000 for a contract that ends in 4 months time which i am paying R99.00 for!!! what the hell is wrong with TElkom and its staff members? is it incompetence of absolute insensitivity and lack of values in as far as customer service is involved???? i am sick of this, rather take your data and i can move over to a more reliable and customer focused service provider!!!
