Groupon - 3 month later still not Refunded

Hello. I write to you after several months of frustration. On 1 November 2014 I purchased 3x 10w LED flood light (2 for 1 special) and 2x 100w LED flood light (2 for 1 special). I should have received 6 x 10w LED flood lights and 4x 100w LED flood lights. Instead 10 x 10w LED flood lights were delivered. The following are the Groupon codes for the purchase: ***3CF, ***BT9, ***WP7 for the 10w LED purchase and ***0NC, and ***4PI for the 100w LED purchase. I informed Groupon (telephonically) of the incorrect delivery around in November and further informed them that the order must be corrected before 15 December 2014 as I will be moving house. I received an email from one Cheslyn van der Heyde who stated that the correct order will leave the warehouse on 14 November 2014 and will be delivered to me within 4 to 7 days. The incorrect delivery will be picked up at the same time. This did not transpire. I then wrote to Groupon explaining the situation and informed them again of my imminent move. Notwithstanding 18 subsequent emails, on this matter, and Groupon's promised to do the refund on each occasion, this has not happened. <br> Please assist. Devan Pillay (***
