On Friday, 25th of October 2013 I upgrade my contract for 24 months for the Cellphone Nokia 625 Lumia (MTN 100 Topup) at Autopage Melrose . On Sunday, 27 October cellphone was not activated and I took cellphone to Nokia Vodaworld Midrand to check and advised that I have to return cellphone is faulty because does not read sim card. <br> Then the following day on Monday 29th October I return to the store to check and found that does not read sim card and I signed return goods form and John advised that they have to return to their Head Office in order to replace it.<br> On the 04th November I called to enquire about the new cellphone and he said he have not receive it yet, he will let me know as soon as they receive it.<br> On the 07th November he called to collect the phone. I went same day to the Autopage Melrose store and request consultant to insert sim card and transfer data. I waited for 2 to 3 hours, Assistant and their co-workers struggling to transfer data due to not paired with any phone over Bluetooth and fails on signal. <br> Autopage deduct full amount including device monthly from Feb 2014 until April 2015 without not having any device. on 18 May they deduct 1237.45 with no details
