customer service agent-poor service

i called pep and the service i got just to a statement , i was assisted by a lady names mendy to transferred my call the 1st time to the wrong department and the call was transferred back to her. she kept asking stupid question like the date i opened my account which i told her i odiously wont remember and later asked to be transferred to a supervisor which she refused to do so. so i called again and spoke o mawethu to put me through to a team leader who was rude as well , did not listen expected me to listen to his whereas he has not hear mu side o the story. he later said i will be emailed a statement which i have not received even now, the company that wants to pay wants an invoice not an sms which is why i want an invoice they tell about 24hrs. such a big company cant even do a simple thing like send an invoice. they tell me i must send a 3 months bank statement to get an invoice how ridiculous is that. the service i got today was by far the worst ever.
