Talkom Service absolutely poor

I am having problem I have been buying data for my WIFI tel no *** throug FNB and Capitec and for over a week I am having problems data gets allocated to their night data. I am running a smaill business and data is essential for me I have been on the phone with customer service a couple of times they cant help me to take the date of the night data at this stage there is about 16GIGs lying there and no one can refverse it you dont have an option when buying data online through your bank if you want day or night data Telkom people at call centre are just dont care...this morning I took my airtime and divert it to data just so ican get on the internet.... I am very unhappy and hope telkom can contact me just not on the data line as it is in the modem my alternative number will be send on request
