Credit that never seems to be coming

I have been waiting a while for a credit store refund. its gotten to a point where i should have just asked for my money back. Their service when it comes to refunds is disappointing. if you don't phone and follow up nothing gets done. I phoned and spoke to Linda about my order being damaged and not working after I emailed them about it more than once before the 25th October. I spoke to Linda on the 25th who requested another email with pictures again which i did. The parcel was logged for a refund on the 29th Oct after I phoned again to find out what was happening about it. First I was told they can't collect the item and then I was told they will collect the item. They were supposed to collect it on the 30th but came that day 29th. I phoned again on the 4th of November to follow up on my refund requesting a store credit - which was promised on that day. Nothing was done I phoned again on the 8th November and I was told it will be done then as someone else was dealing with my order. Now the 11 and i'm still waiting. phoned to follow up again and still no refund. Just we send an email to payments and we waiting. I guess they don't care much about their client so long as they have your money? The follow ups and confirmation of details just gets overlooked. the service with regards to that is just poor and so sad that I the customer has to follow up and beg for my credit.
