Deactivation of My Account of Which is paid in Adv

My dstv account has been deactivated three times in the past week alone cause they are claiming I have not paid my account and that I am also liable for a late payment fee.Initially when it happened I called the call centre an spoke to an agent by the name Mmatseleng Kwinana whom I informed that my account is up to date and forwarded her proof of payment but she never even bothered to even respond to the e-mail itself .I called the again an spoke to another agent by the name of Ntombikayise Kotelo who I also forwaded the proof of payment of which she also did acknowledge receipt but activated my account anyways. A day later my dstv was deactivated again andnits been 2 days of no help no response from anyone. I have spent on average 20min x6 waiting on their call centre to go through but nothing.The same dstv is quick to you send alerrts about paying when in actual fact I pay in advance of 26th day of each month. They reaaalllllly suck!!!
