Bad sising and customer service

I bought 2 pajama sets ,size small, for a xmas present from Intimo. Both tops were like extra large and both bottoms were like extra small. I returned them at my cost($10.00). Intimo did not correct the problem as promised or phone me back as promised. One month later, they emailed me that the sizing was correct. WHAT??? Intimo issued me store credit. NO REFUNDS. Would you have faith in buying here again with the strong potential for the same result at your return cost? Credit card disputes did not help. Don't shop with Intimo!!! I regret it.Intimo Women's 100% Silk Pajama
