Telkom's world class after sales service...lacking

So Telkom boasts world class service and that you are allowed to migrate your package after the first three months of service on a contract to stay competitive with other providers. I was interested in giving Telkom more money than what they are currently getting for a migration of my contract after the fantastic service they gave me when taking out the deal. Well your after service sales sucks. I have been to the Centurion Branch three times over June where i was promised that the consultant would speak to the manager and get back to me since the manager doesn't work over weekends or public holidays, the days people can see them. I then went to two other branches since Centurion failed to respond, who couldn't assist due to system splits. I then had my brother go enquire about the migration and he spoke to the manager. I sent out said email as per request and still have not received a response. Your live chat solution on the website also never works. Can Telkom please have the decency to assist me with a simple yes or no answer to whether i can migrate to a larger package with options, I want to give you more money but you are clearly not interested in this.
