Ridiculous service

I have(had) 2 accounts with vodacom:Phone &computer ***.InOctober I checked to see when updates were due.Phone was in March 2015,computer in October'15.Since Feb.'15 I have not received the usual E mail invoices but a single debit has gone thro bank for the total sum of the accounts.I phoned accounts to find reasons and was told by Selena in contracts that accounts now linked.(without notification)and that contracts now extended to March 2017!!! She was adamant about this and refused any further discussion.I recentlly moved to new accommodation and included in the rental was access to Wi-Fi which suits admirably as Vodacom reception in the area is poor.My Vodafone modem has also packed up.Receiving a State grant is my main income so cancellation of the computer contract would be beneficial.<br> I got an update on my phone in October and received a trash Vodacom Smart 6,Loca lVodacom not very helpful in assisting with operation of this junk!<br> Please could you assist in getting computer contract cancelled<br> Phil Minnaar
