Pathetic service and internal communication

I am so upset with Mr Price. I have had an account with you for years and never experienced this. I was away over December and for the first time missed a payment. They phoned me and was extremely rude. On the 21st of December 2018 I paid R500 which was way more than my installment. They then called and asked me for proof of payment early in Jan as they said they hadn't received payment. I sent through the proof of pahment to ********** Now I receive phone calls daily telling me I now owe even more on my account and I keep asking these people to please make a note that I have paid and get back to me. For some reason there is no one working there with the ability to assist. I am closing my account today and will never advise anyone to get an account from you again.
