Unacceptable poor Mweb customer service

Unacceptable customer service. I cancellerd my service with Mweb on the phone by calling the customer centre. I was politely put through customer retentions. I have fibre with a different provider that offers unshaped and uncapped internet for a much cheaper price. I was told on the phone that my service was downgraded and I would only pay the R59 for the email adreess from 1 September 2018. I then enquired by querying online through the customer portal and they had no record of me cancelling. I then asked to cancel my adsl line and adsl and only retain my email address for R59. There seems to be bad business practice as Mweb seems to keep trying to postpone the cancellation. Now the ticket is closed and I can't respond. I was only informed with the last response that Mweb requires a calendar month notice. This is an extremely bad business practice as other good providers like Afrihost and Axxess you can change your service during the month and it reflects immediately. Now this month I am paying R1162 for 10MBS ADSL line that only works 5/6MBS. My Fibre through Accelerit is R853 and works at 50MBS upload and download speed. I have been a member of Mweb for 20++ years and really upset how badly I have been treated. Since Mweb has merge with Internet Solutions there is no customer service with very bad business practices. I have almost given up trying to cancel my account due to bad service and bad business practices as Mweb almost tries to make it impossible. I will definitely not recommend Mweb to any family and friends due to very high prices and bad customer service.
