Difficulty in Contacting Telkom for Fibre Line Cancellation

It has proven exceedingly challenging to establish contact with Telkom; my emails have gone unanswered, and my attempts to call have yielded no response. Upon visiting a branch in Hartbee****rt dam, I was simply directed to contact the service centre. I wish to terminate my fibre line due to relocating to an area not covered by the service. Despite having paid for two months of unused service, I find myself mostly abroad, making it impractical to visit a branch or incur the expense of frequent international calls. I am eager to know the procedure for cancelling my service, having already communicated this disappointing experience to others in my new locale.
