Worst service and experience

1 star is even to much of a rating for dstv they deserve a negative 0 I bought a decoder last month and an installer came to install for me but I was told I have an existing account and could not activate I went into dstv jhb center and lady confirmed it's an error on their end as I do not have an account and she will have to escalate and after 24hrs my account should be active!! That never happened to a point where the lady who assisted started to avoid me until I activated an account using my sister details,an installer then came to assist again this time charging me 200 because my voucher was no longer valid now none of the channels are working with an error code E48 and I'm told to pay an installer again-why??? Why have I paid to watch what's not working in the first place
