Pathetic DStv consultant in Pinetown

Always pay my dstv account using banking app, now they disconnected my service whilst paid in full on the 25 as usual, when I call them two rude ladies, coloured and black one says they having problem with FNB, so why does that affect me, why didn't they send at least SMS notifying of non payment receipt, why only cutting services on the 27 at night,

Furthermore they say I must send them proof via email, what about people who do not access to such, what about those who do not even know what, how to use that, so they cater for leanerd people only, this is pathetic, and they cannot even explain properly but very rude
