LACK OF COMMUNICATION AND POOR CUSTOMER SERVICE

I made a payment to pay just now Friday the 26 of May 2023 and when i logged in to the app there was no payment reflecting on the app and yet the money left my bank account. got in contact with my bank following day trying to find out what is going on .my bank confirmed they received the money and pay just now took payment from me again Monday 29 of May 2023 sent proof of payment to them numerous times and i last called them on the 1of June 2023 and it was confirmed telephonically that they payment is received. the app is still not update. all they keep doing is to move the date for another payment that should not exist at all. all i hear is that the matter is being escalated. was told by Friday the 02/06/2023 i will receive a call and a way forward regarding the payment that was taken twice. never felt so ignored and inconvenience like this. THESE PEOPLE JUST DONT CARE AT ALL SUCH POOR CUSTOMER SERVICE AND LACK OF COMMUNICATION.
