Pathetic service

I requested my landline to be cancelled on 22 January 2015 after visiting Telkoms walk-in center in Tygervalley, Western Cape. I received a phone bill end February, queried this on my 2nd visit to Tygervalley store, the store assistant told me my cancellation request never went through.<br> i've been to Telkom Bellville, Waterfront and 3 times to Tygervalley, phoned the customer care line without any luck.<br> so after 5 months I'm still being billed and really dont know else to do.
