Worst Service

For weeks now i have been complaining about the faulty internet connection bit nothing all their agents do is is ask a question then disappear without solving the problem. After weeks of battling with this problem I let go only to find out that today Telkom decides to switch off my internet and landline despite me paying my bill each month. The bill was delivered in the beginning of February and paid shortly thereafter in full as I do each month. I am sick and tired of the bad service and nonchalant attitude of their staff. Charging me R400 for 1 gig of data is also ridiculous where are the telemarketers now to offer me a better package? Or does this only apply to certain clients?
