POOR SERVICE FROM MWEB

My E-mail server is run by MWEB and they sold me AVG to stop the SPAM, for which I pay extra. In July the AVG cover is increasing in price and I am not impressed with this as lately I have been receiving lots of "below the belt" emails that are not being stopped by the AVG, so what is the use of paying for a service that I feel does not do what I expect it to do and was told it would do by the salesperson. I would therefore like to CANCEL it and there is not portal for cancellations, and no emails address or contact Number for this type of query, so I tried technical help which did work, as OTP was never sent, so tried again and this time got through to a woman, who told me to hold and then dropped my call after the automatic message said to hold at my call would be attended to 5 times then no service - call gone. PLEASE - CANCEL my AVG that I am paying extra for do not want it as it does not work to my satisfaction. SUGGESTION - when SPAM mail or obnoxious mail is received on your server for clients, it should immediately go into their SPAM folder and not be downloaded to PC, TABLET, PHONE etc; and if they want to check that nothing has slipped through to SPAM folder, clients can personally go onto the server go the SPAM folder delete where necessary - all the FILTH coming through recently is disgusting and upsetting .
