Poor turnaround time for allocation of payment

I had made a credit card deposit on Saturday (which reflects immediately) , I phoned the call center continuously from Saturday and ive emailed proof of payment , they assured me it would reflect on Sunday and on Sunday it would reflect on Monday , I voiced my concerns about my electricity being cut and they said it wouldn’t. My electricity is now cut and my payment from Saturday has not been allocated , everytime I get the same response “we will get them to allocate the funds”. Surely this doesn’t take 3 whole days.
