Would give 0 star if I could absolutely… Recently I visited the O2 Swindon showroom for getting an O2 postpaid SIM connection. Just five months before only I moved from France to the UK as a part of my new job. so my main motive for the O2 prepaid sim was to increase my credit score. But it was one of the worst decisions because due to their continuous hard check of my credit score, I lost 80 credit score (within 5 min !!!!). Also, the respective O2 staff from the Swindon Showroom didn't inform me that they are gonna do a hard check. That is also multiple times???!!!! Still, I don't know how it makes sense to do multiple credit checks and related point loss within a short time (within 5 minutes?!!!) from the same agency?. Now it will take at least one year to recover and now it is adversely affecting my life. I tried to contact O2 customer care so many times and no response at all.
