Vodacom service

I bought an iPhone 8 on the 8th feb and during the week i was out the country when it developed a smurge on the screen.i qas told to return the phone within 7 days for the OBF warranty to apply. I then took it back on the 7th day where i got a rude consultant by the name of Ronnie and was taken from pillar to post until hi was told im not getting a new fone cause my fine had user scratches on the screen and instead they'll fix it. I was also told it will be ready for collection on the 18th of which when i went it wasn't ready. The guy who helped then offered me a loan fone since i didn't have a fone and told me I'll get a message to say it is ready for collection. I eventually got a message today to go collect then i took time out from work to go collect. I was assisted by the lady called Modiegi and to find my fine was not repaired still. First they can't replace now they haven't fixed it. It's costing me business,money, time, petrol to be driving from pta tp midrand for nothing.i mean this is absolutely ridiculous. I ask to speak to the manager the they bring me a technician. I mean if this is how you treat your customers especially the fact that I've been with you fpr more than 10 years im sorry you've lost a customer. The service is just awful....
