My review is based solely on a telephone call I had with Melanie this morning and therefore based on her customer service as opposed to XLN in general. I have had months of trouble with xln and put in a call to query my bill yet again today. I spoke to Melanie who asked to call me back so she could look into it as she could see there have been lots of problems. Melanie did call me back and has gone through the account from the beginning to finally resolve any outstanding issues. She was very helpful and I am very relieved that someone finally investigated this fully. She has resolved the problems and I am very happy with the outcome. She was very polite and professional throughout the call.
