Harassment from vodacom

Recieved calls from this number +*** every morning for the past month, they call me between 7 and 8am in the morning sometimes they just call to say absolutely nothing and drop the call, this is enough to **** one off. This specific lady calls, thanks me for making a payment to my account then goes on to say I need to make full payment before the end of the month. Going back and forward explaining why I'm not able to make full payment she just drops the call and this has happened twice. I lost my job during covid and still busy recovering making ends meet, for someone who is not working I am still making sure to pay R300 onto my account for the times I was not able to pay during level one lock down. I will no longer answer vodacom calls. I will complete my account payment when I'm able to.
