Outstanding customer service. Bought two high end phones — excellent price, items were as described, immaculate. Couldn't fault the experience.
"Bought my son's last 2 phones from these guys. They were brilliant. Even threw in a protective screen and some extra sweets for my boy. Really knowledgeable and friendly."
"Had my Samsung Galaxy S25 repaired today, said it would be done by 2pm and was done even earlier. The repair itself is a 10/10 — brilliant job."
"Sold my old handset to Harrison at Calatech who quoted much more than the competition. Outstanding customer service, as always."
"Ordered a PS5 Pro at a very good and competitive price of £450. Locally delivered within a few hours and in great condition."
"Couldn't recommend more! I've bought my phone, my wife's phone, and our daughter's phone from Calatech — great service every time."
"Excellent service! Sent my phone for a repair which was executed perfectly. All the details were explained clearly and I was impressed with the fast turnaround."
"Came in with a faulty charging port and it was sorted within 5 minutes! Great service."
"Exceptional — sent phone at 4:45pm, money in my account 2pm next day. Gave more money than they offered online."
"Bought an OLED Nintendo Switch just before Christmas. Had an issue with one of the Joy-Cons and Calatech got it sorted quickly with no fuss."
"Brilliant service! I was kept up to date with everything, and payment made the same day as collection! Couldn't be happier."
