Poor service

On 1 March I cancelled my internet package with Telkom because I am moving to Mweb, telling the call centre agent that they must just cancel the internet. On the 15th April my internet was off. Phoming telkom they said I was R300 in arrears. Upon paying that amount and still not having internet I phoned again and the agent told me that my adsl line was cancelled. This was NOT the instruction given to them. The agent said all I can do now is to open a new line. Upon doing so they said it will take 5-8 days. When I phoned on the 25th April the order was onky processed on the 23rd April but in 5 days I should have an open line. I phoned again today, 29th April to see how far the order is on which the agent told me that a technician had to come to the house and replace the line because everything was cancelled. This could take up to 2 weeks. I am now being punished for them not listening to the instruction I gave. I have to pay mweb for a service I cannot use due to Telkom being unhelpful. Is there someone besides the callcentre agents I can speak to regarding this issue??
