worst service recieved ever

i settled my one account's on the 10th of July 2018, just to find out that my other number has been suspended due to being in arrears, I called in on the 24th of July, I was advised that I should send through a proof of payment, I sent it through to a agent , Thandeka Mlotha till this day the funds have not been allocated to the account and my other number is still suspended and nobody seems to be able to assist, my accounts are overdrawn because they keep trying to debt but cannot assist with allocating. absolutely disgusted by the poor service
