NO FEEDBACK AFTER 2 MONTHS

I have been trying for 2 months with no luck to cancel my Telkom line and Wireless internet. I have made numerous phone calls and sent emails. I went into the Fourways Crossing Branch and they completed the paperwork for me and gave me a reference number Ref Number: AI***, they informed me that someone would contact me....I have still received no feedback and I am going into month 3 now. I am beyond Irate and would really just appreciate some assistance!!!
