Appalling customer care service from the Cancellations Department.

I have been experiencing very bad customer service from Vodacom Cancellations on their number *** select #2. More than a month ago I called and cancelled two (2) data lines which have not been cancelled as requested. I am still billed for these numbers, i.e.: ***and ***. I phoned this number again this afternoon between 17h15 and 17h45 to request that these lines be cancelled. I had to keep on phoning back and in total I spoke to four (4) consultants during that period of time and each time whilst speaking to them they disappeared from the line and the line went dead. Please assist me in this matter. Melanie Reinecke Cell #: ***
