Cant contact to cancell service

I have a 10 mb fiber service from Telkom, which has been *****, for +- two days a month typically does not work, and I have tried to watch online content but way to slow, although annoying , the thought of trying to contact customer service has bee more fearsome than the frustrations with the service.

Saturday 28 oct night we had a power failure in Pinelands, power restored some 6 hours later and internet would not come on. on Monday 30 oct I contacted Telkom to report Fiber not working and they told me Account was suspended and no they cant help me or tell me why. I need to contact accounts. After waiting the standard 20 minutes on phone I eventually get trough the someone who goes through my details and then says my account suspended for an amount of R900 and puts the phone down. I have no idea how or where they get this amount from as all debit orders have been honoured. I lost my sense of humor at that point and decided to cancel all my services with the Company I contacted 8ta call centre and spoke to a Thabiso Mohlakoana a Customer Service Representative, who very kindly sent me a Cancellation form and the email address of the people I should send this to.

I sent this on Monday 28 th and again on Thursday 2nd(Today) and received no conformation of receipt. I have phoned 10210 this morning and lady said she could not help I need to contact Fiber dept ( Who are they?) I have also driven to the Telkom store in Tygervall only to be told they cannot help me, they are only a sales office. The service has been on debit order since its inception, and I Note they have taken the debit order yesterday on the 1st. However I don't have a service.

I want nothing further to do with this company, I would like my Mobile number release, and the fiber port released so that I can switch provider.

How do you get a response from this dreadful company.
