Query about Mr Price who doesn't care for the customers

Good day Hellopeter My name is Ntombifuthi Tobotshana,, on the 20th April I bought a cellphone at Mr Price East London Gillwell Mall. I only used it for 10 days,,it started to give me problem with the touch screen. I have decided to return it,,they said they will book for repairs,which is fine. After 3 weeks got an sms saying my phone is ready for collection, I had to travel from Willowvale to East London. When I get there they only tell me that the phone hasn't fixed it's declined by the repairs,,they will book again,,my question is how could they keep me waiting about 3 weeks without my phone,,how can they send me sms to come and collect my phone while they know it's not fixed? I asked for their Area Manager that they kept me waiting for 3 hours and de didn't pitch up.

I am really ****ed off. I have proof of purchase with me
