Pathetic service

Following my previous issues with my line and connectivity with SADV the supervisor promised to give me feedback on why I had no internet for 3 days. To date I've heard nothing. After the connectivity issues and someone from SADV cancelling my line, I put in a request on the 29 Nov to cancel my subscription with SADV, the lady I spoke to in retentions said I must put my cancellation in writing and she will be in touch. To date no one has contacted me everytime I phone in I'm told someone will call me that day. I've sent emails no response instead they're still charging me for the month of January when the line should be cancelled and. I will not recommend SADV to anyone the service is disgusting and the fact that no one phones you back or responds to the email is further proof of how poor the service is. Do not join SADV.
