what's happening with my refund ?

<p> So I was over debited with R120 on the 27th March. I called in last week Thursday and was told that they will log a service request for my money to be refunded.o call in today just to follow up, I am told about different amounts and that a service request was not logged. Despite the fact that Vodacom has had me as a client for over 10years and they have not even given me a sweet I remained loyal and this is what I get? Wow Sterling service </p>
