Hi
@lincy, sorry to hear about your experience! The delays must be frustrating indeed. And there is no consistency in experience, even for people applying for re-mark from the same centre. My BC centre in Mauritius, for instance, told me an EoR typically takes 10-12 weeks but there was a candidate who had applied for a re-mark in July'17 and just received her EoR letter this Feb. For myself, I was one of the fortunate ones, as apparently all who applied for a re-mark for the 10Feb18 test received their EoR letters within 3 weeks.
Do keep following up with your BC centre and insist that you wish to escalate to the Complaints Manager if the delays continue. It is the customer service desk that you are dealing with I assume, and they are supposed to render proper service to their customers, as all us IELTS candidates assuredly are. Once you speak to the Complaints Manager, you can expect a marked improvement in the efficiency and follow-up by the customer services team. Best of luck with your efforts in securing your EoR letter, as well as with the results themselves!
