TELKOM VERY BAD SERVICE

I received the worse service ever from Telkom , they installed new fibre, fibre didn't work they still charged me for fibre as soon as my fibre worked I phoned 3 times to cancel my landline because of new fibre , they still charged me my bill first month was r3216.31 second month r1599.10 3rd month 1621.78 as I have done my new contract with them they told me its only r800 a month but because I didn't pay r1599.10 they have disconnect my fibre now I must still pay r1621.78 end of month but whole month I don't get to use it each and every month I have to phone in and log a dispute on my account they even charged me first month for my device this is a contract looks like Telkom cannot do their work and now they even disconnect my fibre because they cant do their job, and if I phone in they are telling me I didn't pay my account ive paid each and every month the amount agreed as contrac stated and still they disconnecting me fibre because I didn't pay 1599.10 and only paid r800 that I was suppose to pay
