Cancellation of contracts

I originally completed a cancellation form in order to cancel my 2 Telkom Mobile contracts as I will be moving abroad. I sent this completed form on 28/11/2017 according to their turn around time their sla is 21 business days which I accepted. Around the 29/12/2017 I called in to follow up on the cancellation and was advised that no feedback had been received and that it would be escalated to fast track the cancellation and I would receive feedback within 72 hours. I waited but no feedback was received so I followed up again on the 17/01/2018 where I finally received a case number but was advised that due to the wait it would be escalated and I would not have to wait the complete sla again but you can guess I had to follow up again due to no feedback so I called again on 23/1/2018 and again was advised they'd escalate but due to my now growing impatience I requested the details of a team leader. I escalated to Zandile the team leader who copied me in on an email to someone unknown to me due to "internal mailboxes" and now 2 days away from being 2 months to cancel a contract my patience has been pushed too far and hence this complaint! I worked in the service industry so am patient up to a point, but 2 months firstly to cancel contracts is absolutely ridiculous!!!! Besides the lack of feedback from anyone! I've got the trail of emails of each person I've forwarded my cancellation request to (well each time my case was "escalated") and now demand immediate feedback due to this pathetic service!!!
