Disappointing Service Delivery

Good morning, I walked into the MTN Store in Vangate Mall Mitchells Plain where I was greeted by a consultant who immediately assisted me with an updated esim application. All went well until I had to receive an email from their system. an hour later i returned to the store stating I have not received the email notification whereby a second consultant told me the email normally takes a while. Twelve hours later still no email. The reason for my complaint is that the consultant never took the time out to verify if the system had sent the email. Yet the day before when i stepped into a MTN store in Tygervalley Bellville i got an email immediately while i was still in the store. I feel the service delivery in Mitchells Plain branch of MTN sucks and would not recommend it to anyone.
