Telkom patheticly run organisation with no regard for its clients

I am utterly disgusted in the lack of service we receive from Telkom, we have 3 contracts with them one of which we have put in a cancellation for. they keep deducting funds even after payment has been made on our account and then after receiving payment via eft and debiting double the amount they still block our account when you phone accounts they refuse to assist in unblocking our accounts which are now paid 2 months ahead due to them putting through late debit orders for 2 months payments and us having paid via eft because they have a debit order date but they keep changing the debit orders as they like regardless of the amount of times we have given and set a debit order date to ensure there re funds for their payment to go off , even with this said a contract that was up for renewal / cancelation in january has now been put on a month to month service after we have requested muiltiple times that it be cancelled now that they blocked our account they refusing to put the cancellation through as we have again called to have the contract cancelled as its just not been done by them saying that they cant help us now until its unblocked yet its paid 2 months in advance telkom has given me nothing but a headache and stress beyond measure i would rather go without a phone then ever support or recommend them to anyone , i have in my life never come accross such a unmannaged company in my life with staff that only have excuses and no solutions to my problem as well as never doing as a client has instructed and the mannagers are just never available when you request to talk to them so no luck there either i mean if you dont want to upgrade then well just impose a month to month payment plan and refuse to cancell your contract when it comes to end of term they are a pathetic service provided with a accounts department that laze about and sleep instead of ensuring everything runs smoothly for their customers.
