I am writing to lodge a formal complaint regarding my cellphone line, which has been blocked since 29 October. I settled the outstanding amount on the same day, yet my phone is still blocked almost a month later. Since then: I have visited a Vodacom store three times, I have called customer care multiple times, Each time, the call centre’s automated system sends me to TOBi, who promises to send an SMS — but I cannot open the SMS because my phone is blocked. This situation is unacceptable. I have been without calls, SMS, and basic phone access for weeks, which has affected my work and personal life. I have fulfilled my responsibility by paying the account, but Vodacom has not restored my service or provided any effective assistance.
