Disappointed and ridiculed by how Priscilla attended my enquiry at Telkom Promenade Cape Town

Just had the worst service from Priscilla at Telkom Promenade, I accompanied my brother, he was ****** his prepaid cellphone and we went to Telkom with intentions to get a serial number which she gave us attitude saying she can’t provide us anything official regarding our query. She said she can’t give us a prepaid number usage report but only contract cellphones. I asked her to write us something with a stamp so that we can give it as evidence that Telkom doesn’t issue such. She said she won’t do that and that we should call Telkom customer service, I asked for a Telkom customer service number and she asked my brother for the number that he lost and wrote my brother’s number down to show that she didn’t care about servicing us. I am disappointed and saddened that Telkom would hire people with no sense of empathy and respect for servicing customers to satisfaction. We need the repor for a claim, now we can not proceed with the claim because our service provider can’t give us what we need which doesn’t make sense.
