4 Month horror to cancel 24-month mobile contract (after the 24 months!!)

<p>I am assisting in cancelling my 76 year old gran's 24 month contract as well as the add-ons that lapsed in October 2016, but I'm having no joy with the people at Telkom. No one informed her to cancel her contract after the 24 month period, god knows why as the contract was only for 24 months and in the mean time they're charging her for all the add-ons and the data etc.. I emailed the cancellation form on October 14, 2016 only to be told in January the email address they gave me was the incorrect one and I have to email it to a different one to which I got an "recipients email address is full" error On January 5th. This is beyond frustration, *********** a sickly pensioner and no one seems willing to be of assistance there, I gave up enquiring about the status of the cancellation and if they will reimburse her for the services she didn't use. Getting billed on time every month, religiously, mind you.</p>
