Bad Service

I don't know where to start... a payment was made on the 28 Feb 2018 and proof of payment sent to ********** and a request for a call to be made back to me. upon calling no one was able to assist me therefore I was given a number to call of which no one answers that line this has been continues everyday and still no answer... I than called customer care they advised me no payment is reflecting and they can not assist,from the 28th Feb I have been trying to get this resolved. Yesterday I called and asked to speak to a manger and the staff advised me the manger can not assist and I still need to call the ********** 200 I explained that I have been trying that number since the 28th but no one ever answers I was told the waiting period is 45 minutes, I was shocked as I have never heard of a call centre that has a waiting period of 45 MINUTES, I've sent an email to customer service and proof of payment but as always no response i need this to be resolved TODAY please.
