OnAir TV is a ****

I want to warn everyone about OnAir TV. They sold my elderly grandmother a DSTV package on lies, and payment terms, even though she clearly said she depends on a government grant. They kept taking double the money every month until she had to cancel the debit order and go back to her original package. Now, they are harassing her with SMS and phone calls, which is completely unacceptable.I strongly advise caution before dealing with OnAir TV, especially with vulnerable customers.
