Bad services they just not bothered

Every month I make payment via the easy pay option and send proof of payment once done,I made payment on the 27.09.2021 and on the 1.10.2021 I received a SMS saying that I must not forget to pay my account,I call customer care and ask them what's happening the consultant tells me there is no payment showing and I should send proof of payment to the emails adress that they provided me with. Today I call them again to find out if my query has been resolved they tell me there still no payment and I must sent it agen. I ask the consultant I sent it twice in the week why should I send it again she tells me with a stinking attitude they will attend to it on Tuesday. Receipt,bank statement,account statement with easy pay details and SMS showing the amount came off my account was sent. This is a horrible experience
