Waiting for refund after promised date 07 March 2018, now with Telkom having diffrant stories

Hope that hellopeter can assist. I have send in my cancellation forms in on December 2017, They did contact me and all the items was cancelled after i struggled with them to do it. I had to complain at ICASA to get assistance, They promised me that they will refund me in February. A lady called me Marlene Volschenk (MM) Telling she will request my refund in 07 March 2017 that is the time for the final invoice. I emailed her this morning now with Marlene telling me I should contact her only on the 13 March 2017.

I had to many problems with Telkom before so i cancelled this month i moved over to a service provider that will is 80% beter then Telkom, So i want my refund to pay my new service provider before Friday, Marlene Volschenk told me that i would be having my refund just after the final invoice.

What should i do. Because i waited 2 years for Telkom for service delivery. But that was not going to happen ever.
