Data

I have had a contract with Telkom for the past 10years and never in these 10 years have I ran out of data like the last 2 months. I have wifi at home and at work yet my mobile data o ly lasts a week or even just a day.. I have never run out of What's App data before but now come the second last week of the mnth I have to buy data which only lasts 2 days.... Is there any other people out there experiencing the same thing with Telkom. I have 2 contracts with Telkom and both have thr same issues. I also have about 20 friends that are experiencing the same problem. These network service providers are really draining our pockets in this time. They have to be brought to task.
