Bad Service

I am very disgusted at the service provided by Telkom. We were in the process of closing one of our Future Finance branch (Pmb2) in Pmb. We followed the necessary steps & provided Telkom with the necessary documents (ie. 1. a cancellation letter on our company letterhead including the physical address of where the line has to be disconnected; 2. a copy of our Telkom account for the branch where the Telkom line needed to be cancelled). The notification period is one month. The email was sent on 28/08/2019 meaning that on 28/09/2019 the line would be cancelled. However, come 30/09/2019 Telkom cancelled the line at the wrong branch (Dundee branch). On 02/10/2019 I received an email from Telkom confirming, the cancellation of our Pmb branch. However there is no-one who can give me feed-back as to the reason the wrong Telkom line was cancelled. We are a cash loan company & this is our busy time. We have lost thousands of rand in business. But of course Telkom just does not give a damn but should a client be late with payments, then the line is cut-off immediately. Their service is really disgusting.
