Bad service

I do not know what else to do, I have an account with mixtelematics, was in arrears and paid, accidently used my initial and surname as ref intead of account number...this happened 22/03/2024....I sent an email and proof of payment for it to be allocated to my account...waited and sent it again 09/04/2024 ....no response from them....Again 15/04/2024 then called...was told it was sent for allocation as the email had been received....I waited again....called today, waited 12 minutes before could assist me...was told again that it received and was sent for allocation on the 12/04/2024...Kanti how long does the process take really.... With this type of behavior, how can one trust that you will respond quick should anything happen to my car.... when alone you don't even answer the phones....Allocate this payment please I have been patient enough...
