Poor customer services from Jet

I received poor service from Jet.On the 07th of March 2024,i received an Sms from Jet,telling me they have not receive payment for February. I contacted them the following day using the number provided by them for enquiries.

A call was received by a lady who tried to transfer my call to the relevant consultants.The phone keeps on ringing.I tried several times up until the lady took my ID number and cell number and promised they will call within 15min.

After about one hour of waiting,i decided to call.The phone is ringing non stop,no one is picking up.My concern is my credit record.I did make a payment on the 29th February 2024.I wanted to check whether the problem was on my side or theirs,also to send proof of payment.

A good credit record is very important to me.And i know once they list you as a bad payer it would be difficult to clear.
