Fibre connection

I've been with home connect for the past 4 years now on a month to month contract they had been 1 of the best service providers with Fibre connect which is the only reason I stayed with them this long and didnt mind paying their fees as of recently they have increased my monthly account fee twice and still I was happy to pay and every payment on time... Although I am extremely ****ed of as this month my internet bill came to R1717 which they set a debit order to come of my account without my knowledge or approval secondly I had still paid my normal R800+ two days before the month could end so in total they would have taken R1717 plus the R868 when I reversed transaction for the R1717 since Saturday I've. Been trying to get in contact with them to ask why was I billed this much no1 has answered or returned my calls or emails and then they send a text to say if I don't pay that funds they will suspend my internet mind you they had also sent me an email last month saying that my cancelation was approved yet I didn't ask for 1 at this stage I just want to terminate all dealings with them completely and move to another service provider 1 that's more applicable I am extremely disgusted and aphalled by home connect I would not recommend them to anyone else in future this is *****!!!
