Quick to debit but slow to refund

<p>I received a call from a Yellodata consultant and signed up for 500mb pm, debit went off my acc for R69 and data was loaded but i was unable to use it. I called and was told that i need to change my APN which i explained i have done this many times. In the following month i got another call for the same product at R89 i told the consultant i have already signed up she told me i dont reflect on the system, about a month later - same thing for an increased price.. by then i was debited twice and had received my data for the 2 months but in all this time i was not able to use the data. I called and cancelled and sent an email as well requesting a refund on 31/05/2017. Today is the 05/07, still no refund and in this time i have followed up twice and all i get told is that they're still awaiting feedback from accounts.... When will i get my refund??? Quick to debit and slow to refund!</p>
