HAVE NOT RECEIVED REFUND SINCE 9 APRIL!!!!!

Due to travel disruption, i cancelled the rental pick up from liverpool and book a new rental pick up from London. I was advised credit will be deposited 5-7days. Since 9 april till now, i have not received my refund! They sent an email to me stating refund credited into card ***x. After i called up, they say it's a typo error. They are very fast to charge the new car rental but it has been 21 days. I have not gotten my refund<br> I called numerous time and exchanged email. They said refund has been done but where is my money!!! <br> I'm very frustrated and shocked by this so called \reputable"company. After i read thru the list of complaints against Avis"
