Contract cancellation ignored | unwarranted bill

I submitted my documentation to cancel my (truly awful) Telkom Mobile contract (which I have been trying to get out of for 18 months because i can't make or receive a call nor get consistent internet on their so-called \network) on 9 March 2016. I sent the cancellation form + my ID + my last bill so there could be no mistaken identities. Of course the email address doesn't send any sort of useful reply or confirmation / ref number.<br> <br> I have called a few times to check on my cancellation & was told that i would be contacted when my cancellation was being dealt with, which would be within 21 days.<br> <br> On 1 April, 21 days later & the date that all my sign-up paperwork cited as my last day I called and was told I had to submit another form. I asked what would happen with billing and was told \"you will be charged with the usual monthly fees as you will be credited with the benefit\".<br> <br> My bill now has R349 for 1gb internet on it. I never ever subscribed for this. My contract had FIVE gb added value, so there's no reasonable expectation that I might want/need ONE gb. <br> <br> Seems like my cancellation was conveniently ignored to get the last pennies from me.<br> <br> Keep it Telkom, but cancel me TODAY!!!!"
