Very rude manager and bad service I’ve been getting from Pep

I’m a business person and I use Paxi to send the parcels and it’s was very convenient for me until today. The manager of the store told me I waste their time because of the parcels I sent apparently they are too much for them , mind you I spend +-15000 a week at pep buying Paxi plastic so I don’t understand why can’t I receive the service as I am a customer paying with my money, she told me that she got that information from her Area Manager so now I must register parcels with my phone at home and I’m struggling with network I don’t have a problem doing that but because of network I can’t hence I choose Paxi it was convenient for me because they can register the parcels at Pep. I’ve been doing this for almost 2 years now so why is it a problem now and I’ve been a loyal customer so I just can’t accept this kind of service really not after spending so much with Paxi. Or should I opt for another delivery service since well you are failing me as your customer . I’m running a business so as for me I can’t fail my clients because Pep and Paxi they are *********** and they have bad service and as they told me I’m wasting their time by spending my money at the shop. I wrote them an email at Pep customer service and Paxi no response nothing’s even now it’s been two weeks, clearly they don’t take us serious as their customers.

The pep is P6320 Phumula shopping centre

I’ll be waiting for the response.
