Telkom PATHETIC SERVICE

I recently contacted Telkom to have my landline number changed and i dialed the sales no. 10213 and held on for 35min and was disconnected. i tried the 10210 number and finally was put through to an agent by and told her that i wished to change my number but the sales dept. kept me holding for 35min and asked her to transfer me to the correct department in which to change my landline no. and the agent put the phone down on me. THIS IS ABSOLUTELY DISGUSTING PATEHETIC SERVICE and i will be cancelling my landline and ADSL immediately if this is how Telkom agents conduct themselves.
