Failure to effect contract migration/bad attitude

For the past 2.5 weeks, I have visited the Telkom shop at Greenstone Hill six times. I requested to migrate my 10GB LTE contract to 50GB. I was approved but sales persons in the shop failed to conclude the migration due to system failures. They logged call with Telkom's IT but still, my migration is not resolved. I have now reached a dead end because there is no way forward offered by Telkom. <br> <br> The attitude by one of the sales persons is terrible (and he is very rude).
