Psi-super (********)

I had a Ro pad water treatment system installed at my house in 2015 and at the same time the technician suggested that I should get a Service plan for a monthly fee of R90 (linked). With this service plan. I was supposed to get a annual free service and replacement of filters and parts. I tried to get a hold of them in 2016 but failed. Same story in 2017. All the numbers on facebook and the internet are incorrect. Even the adresses given are occupied by different companies. The installment for 2018 is R108.90 . This debit order can only be cancelled by them (Psi-Super). But I still cannot get them on the phone or email or even facebook( where they remove my posts for help promptly). These guys are leaches on the hard working people of this world.
