R1000.00 Monthy billing lost, at a price of a Pie.

I have been a client of Vox since October 2023. I currently spend around R800.00 per month. I recently wanted to add a Voice Account for R29.00 and to my amazement, I got declined. So here is my thinking. Vox is telling me I cannot afford R29.00 extra on my account. That is a 2L Milk or a Pie at the shop. I then decided that if my current R800.00 is not good enough then let me move. My Fibre is ****, and always dropping so let us investigate. M web is offering R69 for 150 mins. Vox is R29 then R0.46 p/min. Calculations (R69.00 - R29.00 = R40.00. R40.00 / R0.46 p/min gives me about 87 minutes. Conclusion R69.00 with Mweb is 150 Mins, whereas R69.00 with Vox is 87 Mins. Thank Vox for declining my R29.00 order, because now I can get it cheaper from another place. So you now have potentially lost R1000.00 billing per month, for the cost of a 2l Milk or pie from the shop. Good sells sense.
