Unallocated payment

Good day. On the 20th of May 2021 i paid my Dstv account through internal transfer. A week later on the 2nd of June my viewing was cut. Upon enquiry i was told that the reason for that was because i didn't pay and that i should sent them my proof of payment, which i did. Since i have spent over R200 on airtime trying to get them to reconnect me but all my efforts were abortive. Every agent i spoke to promised to assist but nothing has happened until today. I was told that my payment was allocated to someone else's account and that i should wait for for their investigations and only then they will be able to allocate into my account. What surprises me is the how part because i have been using the same method of payment for many years and never encountered any problem. My reference is exactly it should be. My account number is ***3
