We get contacted constantly by other companies but we would never leave ADSI as the service is fantastic and our Accounts Manager is brilliant – he helps with all queries and is knowledgeable, friendly and  we feel confident that he  gets us the best deal. Many companies we’ve used over the years have been in it for the money only but with ADSI we feel that they really do put the customer first, can’t praise highly enough.”

We receive a personalised service and he is always on hand to advise us on maximising our telecoms whilst keeping an eye on budgets, all without compromising the high level of standards we have come to expect.   Because of this we have moved all our mobile needs to ADSI which goes against normal company policy where we by principle never use a sole supplier.”
