Bad service at Dstv

I paid my account on the 26th February 2018 using the account details i always used just this time i used my nedbank account and i always paid using standard bank. So a week later i got sms saying my account is in arrears i must settle before they cut the decoder off. I called in and spoke to Bongiwe Mxali and she said i must send her an email with proof of payment. I did as requested and i called again then spoke to Duma Ncebakazi she told me the same thing and i also send her the email with proof of payment but still i got the sms two days ago and this morning i woke up my decoder off. I really don’t understand this because i paid and i used the correct details for their account and my reference was also the correct one. Now they say i must pay R483 and reconnection fee, i won’t pay for something i already paid for and with the service I’m getting from Dstv I’m even thinking of canceling my services with them. I’m not happy at all and i feel like I’m not treated like a paying customer who was loyal for so many years yhooooo My email is ********** Please help me sort this out HelloPeter
