Poor customer service

Hi ,this is a complaint for nimble collections . For as long as I set up the arrangement,payments are made each month via a debit order nimble has set up !!!every single month as soon as the payment is made ,please read that again ,the minute the debit order goes off ,I get a wats app,sms ,email exactly after it goes off that they have not received payment ,1st time i called they had received a payment and all but yet im harassed and made to feel like im not paying ..today you guys call to tell me they didn’t receive payment but your consultant says last payment was 28th June meaning payment is in order and made on time ..I feel this is harassment for a person making payment each month .i don’t need a call or any response .just fix your system and stop harassing people making payments on TIME!!
