Mr. Price Mobile not taking my ********** case seriously and taking to long to reimburse my refund

Good day,

I took a cellphone contract with Mr. Price Mobile about 10 years ago that i was offered and stopped using their Sim card 2 years later when my contract ended. From the beginning of 2020 i started paying more on my Mr. Price account and could not understand why until i paid off everything and my account was on a 0 balance. Then the beginning of June 2020 i received a notification saying I'm due to pay R700 on my Mr. Price account. I then called in to find out where this balance came from and i was told that i had been buying airtime for my Mr. Price Mobile Sim card which has never happened. The company is taking too long to investigate and refund my money and i am very unhappy about it. I also called in the offices yesterday and asked to speak to Jeanel from Mr Price Mobile Support whom has been investigating my case and she refused to speak to me and sent a message that did not make sense to her colleague to tell me. I then asked for my issue to be escalated and was told that the Mr. Price Mobile Support manager was in a meeting and would call me back which he never did.

Regards Nicole
