Billing for expired services

After receiving excellent services for years I have had numerous problems this year...

This time I am complaining about additional services that I had for free from 2 ********** which has according to me then lapsed (it was a ADSL plus 2 sim cards with 1g of data each 2 sim cards with 100 min each) and the accounts were dormant since last year. Some BRIGHT SPARK then instructed another person to reactivate 4 defunct services at r276 pm and now are billing me R108.58 x 4 on services that I did not use.... leaving me with a R1600 bill for this month which should have been the R800 odd rand for my ADSL. no joy since logging this request. No joy with phoning (system off line) could you kindly sort this out...
