On Monday 26th August I had a windscreen chip repair done on my car. Unfortunately the screen cracked more so I was advised to have a full windscreen replacement and it would be classed as the same job. I'd already paid £15 excess for initial repair so was told it was £85 extra to pay as it was £100 excess for windscreens. I then kept receiving sms messages and emails asking for £100. I spoke on a customer service chat that same evening and said it would be rectified the following day. It wasn't. I called customer services and she said she'd sort it out. She didn't. All weekend I received reminders of £100. Monday 30th, day of windscreen replacement, I called again. I was told the technician was aware and would charge £85. He had no idea and was told it was £100. Rang customer services again. Was told it would be sorted and I paid £85 to the accounts on phone service. I then continued to receive demands for £15 on sms and email. I rang again and was again reassured it would be rectified. It wasn't. I then received a postal demand for the £15. I spoke to another customer services person who said, yes, there'd been an error on booking the jobs on their end and that the two jobs had not been put through as a single job but two separate so it looked like I'd not paid enough for the windscreen replacement. I did vent my frustrations by this point as contacting them five times and still getting nowhere I was losing patience. Again i was told it was sorted and the open account was closed. It wasn't. I received another letter. I spoke to a customer services manager on September 12th. He said yes, he could see what had happened, was apologetic about it not being rectified properly and promised he would do it and would send £25 to cover my wasted time and phone calls. I received a confirmation email. To my absolute horror, I received another demand today, September 17th for £25 now! They've actually put the amount up!! I can't get hold of a single person to help so yet another weekend suffering anger, frustration and disgust at their shear ineptness. I'm seriously at my wits end with this company. I feel like I'm being treated like an absolute nobody, like what I say doesn't matter, how I feel doesn't matter!!! They are completely incompetent and inept and I feel exhausted by the whole nightmare.
