Terrible service

I made a call to Telkom in April as my contract is due to expire on the 29th of May, spoke to Mahlatji Magaboke who proceeded by sending me a cancellation form and an email address to scan it back to. I have been attempting to send the form back to telkom to the email address provided, and havent been successful, as email s are not being delivered, reason provided by telkom: the email address doesnt exist any more. Which was flipping strange as it was provided to me not so long ago. Upon doing a follow up with telkom today (07/07) i spoke to Nonhlanhla who further advised that the cancelation process have changed, i now need to log on theor their site for such request. Explained to her that their stupid network seems to have stoped working for me as ive been failing to access their site or anysote for tht matter. I need to send the form to someone to action my request , i then Requested to speak to her manager, Nonhlanhla kept on hokd for +20 min, only to come back to tell me that her manager is on a another call , told her it was fine, n that ill wait. Waited another +20min before she decided to drop my call. Made another call immediately therafter and asked to speak Nonhlanhla's Manager, once again i was kept on hold before my call was disconnected. Ive wasted over 3 hours of my time today dealing with consultants who dont understand what service is, All i need confirmationif that my contract will be terminated on the 29th of May and wont be dealing with horrible people emplyed by Telkom anymore. Would be appreciated if i am contacted back my higher management at telkom regarding this ****y service they provide. Worst service ive ever received
