BAD BAD SERVICE

Good day<br> I am writing this complaint out of despondency. I upgraded to an iPhone 4 last year October. I received the phone last year October, every month my I phone is in for repair or exchange<br> Here is my record history :<br> Job # ***5 (18/11/2014) - Imei: ***<br> Job # ***6 (26/11/2014) - Imei: ***<br> Job # ***3 (23/01/2015) - Imei: *** (exchange unit)<br> Job # ***2 (03/02/2015) - Imei: ***<br> Job # ***6 (11/02/2015) - Imei: *** (exchange unit)<br> Job # ***1 (10/03/2015) - Imei: ***<br> Job # ***1 (20/03/2015) - Imei: *** (exchange unit)<br> Job# ***9 ( 25/05/2015_ Imei: *** <br> <br> I have sent a letter to request I don't want an I phone again otherwise they must rather cancel the contract but the people at Vodacom Repairs Escalation don't want to listen to the client , because yesterday , they have sent me an email to tell me that they exchanged my I phone again after I asked them not to exchenge it with a iphone <br> <br> This is pathetic!!! How many times must I ask them for a other contract? <br> <br> I will not accept the exchanged Iphone!<br> I am paying for a phone that I can't use !
