Revolting service

Earlier in the year i had an issue where my iPhone which is under warranty stopped working, i was advised by MTN to take the headset back to the store it was purchased at for a warranty assessment to be concluded.<br> <br> The phone was booked in by the store- and i was advised by the consultant that the process takes between 10-14 days before feedback is received, by the end of 14 days i received no feedback and by day 20 i visited the store and was told they had no feedback from the repair centre, they assured me they would call me in two days but nobody called, again i visted the store for feedback and nothing, a day later after my 3rd visit i requested and address and phone number for HSVC, i went to HSVC and they had no details of the phone.<br> <br> After my sixth visit to the store i went directly to HSVC and they had confirmed my phone was to be replaced, i requested to see the manager Michelle (who has displayed a putrid attitude since the birth of this issue).<br> <br> She refused to see me and shouted from her office at the back of the store that she is too busy and unable to assist.<br> <br> I am now told that they will replace the phone and i become liable for all costs,legal intervention is required
